Measuring Degree Of Match By Importance Of Need And Credibility Of Attributes

Abstract:

A method and a need matching system (NMS) determine a degree of match between item profiles with item attributes with varying ratings of varying credibility and need profiles with need attributes of varying importance. The NMS receives a first attribute list including the item attributes and a second attribute list including the need attributes from an attribute list database and creates a unique attribute list including unique item attributes, a merged attribute amount measure corresponding to each unique item attribute, and a merged credibility measure indicating credibility of the merged attribute amount measure by performing merging actions on first tuples in the first attribute list. The NMS generates a need match score by processing an attribute match score with an importance measure. The attribute match score is generated for each need attribute in a matched attribute list created by matching the unique item attributes with the need attributes.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to and the benefit of the provisional/non-provisional patent application titled Measuring Degree Of Match By Importance Of Need And Credibility Of Attributes, application Ser. No. 62/694,439, filed in the United States Patent and Trademark Office on Jul. 5, 2018. The specification of the above referenced patent application is incorporated herein by reference in its entirety

BACKGROUND

Many items for which there is a need, for example, products, and/or services, and/or persons are associated with various domains. For example, job seekers have skills and jobs need skills. People need medical treatment, and this need is met by medical practices that provide treatments. A battery may be required for an electronic device, and batteries are available for the devices. A person looking for a romantic meal may desire certain food items and live background music, and restaurants are available that provide food items and music. However, items and needs vary and may not be identical. For example, one restaurant may excel in music but provide only acceptable food, while another may excel in food but only provide acceptable music. A person looking for a romantic meal may value music highly, while another may value food highly. Therefore, there is a need for matching items to needs while taking into account the importance of different aspects of the needs.

Consider an example where job seekers enter an employment marketplace. There is a need for finding jobs that the job seekers may fill. Often the matching of a job to a job seeker is based on a description of a job opening being compared to a resume of a job seeker. However, resumes of job seeker are often inaccurate. Therefore, there is a need for matching a job seeker to job descriptions using information beyond that disclosed in a resume created by the job seeker.

Descriptions of items created by providers of the items often lack desired information, or are inaccurate, for example when they describe only the best attributes of an item, or even when they substantially misstate the attributes of the item. As used herein, item refers to an entity, for example, a product such as a battery, a cell phone, etc., or a service such as a teeth cleaning service, or a person offering a service such as a doctor, a job candidate whose service is the skills the job candidate brings to the job, etc., or any entity that can be characterized by attributes. Dissatisfaction with an item often results when the need is filled by an item where the required attributes of the item are not present in the item. The need may be performed inefficiently by the item, and the need may have to be filled again soon. Hence, there is a need for matching items to needs, even when attributes of the item are discovered using information beyond that disclosed in a description created by the item provider.

An alternative source of information about the attributes of an item, for example, music quality, is ratings provided by those claiming to have used or who possess knowledge of the item. As with the information disclosed in a description of the item, the ratings provided by people may be inaccurate, possibly from personal bias or possibly from a lack of knowledge about certain attributes possessed by the item. Furthermore, while using a computer system to determine whether a rating provided for the attributes of an item is accurate is not feasible, the computer system can be programmed to assign a credibility measure to the rating and the credibility of the rating can be a factor when using the rating to match an item to a need. For example, a person who is known to have actually used the item may have a higher credibility in their ratings than one who has not. Or, a user who gives only the best score to every attribute may have their ratings considered less credible. Hence, there is a need for including ratings provided to the items, and also the credibility of each of the ratings, to an item and a need.

Needs often differ. Some of the attributes of an item may be unneeded, others may be required, and only certain amounts of the attribute may be needed. For example, there may be a need for a battery with a 2-year shelf life. One need may consider additional shelf life to be highly desirable, while another need may not consider a longer shelf life to be important. Needs can be characterized by amounts of attributes needed in an item and the importance of those attributes when comparing items to the need.

The number of items that may be considered for a need is generally much larger than a person trying to fill the need can actually consider for satisfying the need. The person seeking to fill a need would prefer to consider only the most suitable items. Conversely, a job seeker would prefer to participate in an interview process only for the jobs for which the job seeker is likely to be a good fit. To identify the most suitable item for a need, there is a need for computing a single numerical score derived from the ratings of the attributes of the item and the credibility of each of the ratings, where the computed single numerical score can be used to sort the highest scoring items to present to the person seeking to fill a need. Hence, there is a need for including the ratings of attributes of the item and credibility of each of the ratings, into a comparison against a need that results in a computation of a single numerical score.

Hence, there is a long felt but unresolved need for a method and a system for determining a degree of match between item profiles with item attributes with varying ratings of varying credibility, and need profiles with need attributes of varying importance by computing a single numerical need match score.

SUMMARY OF THE INVENTION

This summary is provided to introduce a selection of concepts in a simplified form that are further disclosed in the detailed description of the invention. This summary is not intended to determine the scope of the claimed subject matter.

The method and the system disclosed herein address the above recited need for determining the degree of match between item profiles, for example, job seeker profiles, profiles of restaurants, profiles of physicians, profiles of products, etc., with item attributes, for example, skills and core traits, with varying ratings of varying credibility, and need profiles, for example, job descriptions, food item choices of customers, health conditions of patients, etc., with need attributes, for example, job description attributes, skills of the physician for treating the patients, skills of the restaurants in preparing the food item of choice of the customers, of the needed amounts, etc. and varying importance by computing a single numerical need match score. The method and the system disclosed herein relate to how item profiles are matched to need profiles. The method disclosed herein employs a need matching system comprising at least one processor configured to execute computer program instructions for determining a degree of match between the item profiles with the item attributes with varying ratings of varying credibility, and the need profiles with the need attributes of varying importance and amounts needed. The need matching system computes the single numerical need match score for the degree of match between possessed attributes of an item, for example, a product, or a service, or a person, and needed attributes for a need. The need matching system invokes the method disclosed herein separately for determining the degree of match between different combinations of possessed attributes and needed attributes, for example, by matching the possessed attributes of multiple items against the attributes needed for multiple needs.

The need matching system receives a list of attributes present in item profiles and a list of attributes needed as mentioned in need profiles provided by entities, from an attribute list database. The attribute list database comprises predefined item attributes and need attributes that form the list of attributes present and the list of attributes needed respectively. The item attributes in the list of attributes present occur multiple times with different corresponding amount present measures and different corresponding credibility measures. The list of attributes present is not a unified list. The list of attributes present comprises the item attributes relevant to the item, for example, expertise in Microsoft Word of Microsoft Corporation when the item is a job seeker, capacity when the item is a battery, ambiance when the item is a restaurant, neurology when the item is a medical provider, etc. The item attributes in the list of attributes present have corresponding item attribute amount measures and credibility measures indicating credibility of the item attribute amount measures. The list of attributes needed comprise the need attributes relevant to the item required to satisfy the need. The need attributes in the list of attributes needed have corresponding importance measures, corresponding requirement measures, and corresponding attribute amount needed measures.

The need matching system processes the list of attributes present and generates a unique attribute list, that is, a merged list of attributes present in the item profiles. The merged list of the attributes present comprises each attribute in the item profiles occurring only once with a merged amount present measure and a merged credibility measure. The need matching system matches the merged list of attributes present by item attribute to the list of attributes needed. The matching results in a list of attributes comprising matched entries with a merged amount present measure and a merged credibility measure, an is required (ISREQ) measure, an importance measure, and an amount needed measure. The need matching system computes an attribute match score for each of the matched entries in the merged list of the attributes present. The need matching system computes a need match score defining the degree of match between the possessed attributes of an item and the need attributes for a need by combining the computed attribute match scores. In an embodiment, the need matching system assigns default values to the merged amount present measure and the merged credibility measure when the item attribute is not already in the list of attributes present.

The list of attributes present in the item profiles is generated by operational systems of entities by an assessment of the item attributes present, for example, from reviews of the item profiles and descriptions of the items. The assessments result in identifying an item attribute, and a corresponding amount present measure, and a corresponding measure of credibility of the amount present measure. The list of attributes needed is generated by the operational systems of the entities on assessment of the need attributes needed, for example, from extracts of the need profiles. In an embodiment, the list of attributes needed is generated by the operational systems of the entities using questionnaires. The assessments of the need attributes include identifying a need attribute, indicating an is required (ISREQ) measure of the need attribute using a flag, a measure of the importance of the need attribute, and a measure of the amount of the need attribute needed. In the list of attributes needed, a need attribute is present only once.

The need match score indicates a match of one need profile against one item profile. The computation of the need match score comprises credibility of the assessments and importance of the item attributes to the need, for example, a nearby romantic restaurant. Furthermore, the method for computing the need match score considers the core traits of the items and includes default values for an item attribute amount measure and a credibility measure for unreported core traits.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates a method for determining a degree of match between item profiles with item attributes with varying ratings of varying credibility and need profiles with need attributes of varying importance. As used herein, item refers to an entity, for example, a product such as a battery, a cell phone, etc., or a service such as a teeth cleaning service, treatment provided to patients by hospitals, a job role in an organization performed by an employee, etc., or a person or an individual offering a service such as a doctor, a job seeker whose service is the skills the job seeker brings to the job, a tradesman offering certain services such as work on cabinets at a low price rate, an organization such as a hospital, a company, a restaurant, etc., or any entity that can be characterized by attributes. In the method disclosed herein, item attributes are to be matched to need attributes. As used herein, item attributes refer to attributes of an item for filling a need smoothly and efficiently. The item attributes for a product comprise core traits of the product. The item attributes for a service or a person comprise core traits and/or domains of expertise of the service or the person. Also, as used herein, need attribute refers to a core trait and/or expertise desired out of an item for carrying out a need smoothly and efficiently. The method disclosed herein employs a need matching system 200, as illustrated in FIG. 15. The need matching system comprises at least one processor configured to execute computer program instructions for determining a degree of match between item profiles with item attributes with varying ratings of varying credibility and need profiles with need attributes of varying importance.

A first attribute list comprises the item attributes and a second attribute list comprises the need attributes. The item attributes and the need attributes are stored in an attribute list database by an operational system, for example, a recruitment system of offices, educational institutes, etc., a hospital information system of hospitals, etc. In the attribute list database, the item attributes and the need attributes are classified into core traits and domains of expertise of items such as services or persons, and classified as only core traits for items such as products. As used herein, core traits refer to distinguishing qualities of the items. The core traits are possessed by all items in the need matching system, while the other traits are possessed by some items. For example, every product has quality and durability; every doctor has bedside manner and communication skills; and every restaurant has service quality. The core traits comprise, for example, dependability, integrity, confidence, responsiveness, punctuality, communication, cleanliness, ambience, etc. The core traits in the first attribute list and the second attribute list are flagged using an isTrait flag as exemplarily illustrated in FIG. 12M. The domains of expertise are specific to the items. For job seekers, the domains of expertise are job attributes, for example, Microsoft Word, hypertext preprocessor (PHP) programming attributes, etc. For restaurants, the domains of expertise are the expertise of the restaurant in certain food preparations, for example, chicken soup, pepperoni pizza, etc. For physicians, the domains of expertise are knowledge in a specific domain such as orthodontics, orthopedics, pediatrics, etc. For physical items such as products, the core attributes comprise, for example, color, electrical capacity, size, quality, and durability. The first attribute list and the second attribute list are stored in the attribute list database. The item attributes in the attribute list database constitute the first attribute list and the need attributes in the attribute list database constitute the second attribute list.

The first attribute list is a list of the item attributes possessed by the items, stored in the attribute list database, that the need matching system matches to a list of need attributes required for a need, in the second attribute list. The need matching system matches the item attributes of, for example, physicians with the need attributes provided by the patients. That is, the core traits of the physicians, for example, responsiveness, punctuality, communication, etc., and the domains of expertise of the physicians, for example, laparoscopic knee surgery, coronary stents, liposuction of thighs, etc., are matched to the list of core traits and domains of expertise the physicians have to possess for the treatment of the patient. Similarly, the need matching system matches the item attributes of, for example, restaurants with the need attributes needed for serving customers successfully. The customers define the need attributes that are desired from the restaurant. The core traits of the restaurant, for example, cleanliness, ambience, view, etc., and the domains of expertise of the restaurant, for example, expertise in different food preparations such as chicken soup, pepperoni pizza, chocolate cake, etc., are matched by the need matching system to choices of the customers to help the customers select an appropriate restaurant.

An item attribute in the first attribute list has a corresponding item attribute amount measure and a corresponding credibility measure indicating the credibility of the item attribute amount measure. From the item profiles, for example, job profiles such as resumes or reviews of the job seekers, profiles of the restaurants, profiles of the hospitals, a rating of the proficiency of the item is provided by a reviewer associated with the items. The ratings apply to any attribute of the item provided by the entities, for example, the companies, the job seekers, the physicians, the restaurants, etc. As used herein, item attribute amount measure refers to a quantized value of the proficiency of the items in the item attributes. The item attribute amount measure is a numerical value between 0 and 1, both inclusive and NULL. The item attribute amount measure represents the degree to which an item attribute is present. A value of 1 of the item attribute amount measure indicates that the item attribute is present to a maximum level possible, that is, the item is highly proficient in the item attribute. A value of 0 of the item attribute amount measure indicates that the item attribute is not present, that is, the item does not possess the item attribute. A value of NULL of the item attribute amount measure indicates that the item attribute is not known. The item attribute amount measure is a fraction of a total attribute amount measure of the item attributes possessed by the items. An item attribute, for example, the ambience possessed by the item, for example, the restaurant is rated by the customer and an item attribute amount measure of 1 is awarded by the customer. The item attribute amount measure of 1 for the item attribute, ambience, indicates the ambience offered by the restaurant is excellent. The core traits in the attribute list database have corresponding default values for the item attribute amount measure and the credibility measure. In an embodiment, the core traits in the attribute list database do not have corresponding default values for the item attribute amount measure and the credibility measure. In another embodiment, the item attributes in the attribute list database have corresponding default values for the item attribute amount measure and the credibility measure.

The operational system of an entity estimates the credibility of the item attribute amount measure corresponding to the item attributes and assigns a credibility measure based on the estimated credibility to the item attribute amount measure. The credibility measure refers to a numerical value between 0 and 1, both inclusive and NULL. The credibility measure represents the probability of the item attribute amount measure being accurate. For example, an item attribute amount measure for an entry, that is, an item attribute, in the first attribute list with a credibility of 0.9 is treated to represent that the item attribute is actually present or is true 9 times out of 10. The credibility measure is a positive number less than 1 and represents the probability of the item attribute amount measure being accurate. Furthermore, any particular item attribute may be present multiple times with possibly different values for the item attribute amount measure and the credibility measure in the first attribute list.

A need attribute in the second attribute list has a corresponding need attribute amount measure, a corresponding requirement measure, and a corresponding importance measure. As used herein, need attribute amount measure refers to a quantized value of the proficiency of the items required for the need. The need attribute amount measure is a numerical value between 0 and 1, both inclusive. The need attribute amount measure represents the degree to which the need attribute is required. A value of 1 of the need attribute amount measure indicates that the need attribute is needed to a maximum level possible and a value of 0 of the need attribute amount measure indicates that the need attribute is not needed. A value of 0.2 of the need attribute amount measure indicates that only 20% proficiency in the need attribute is needed from the items for the need. The need attribute amount measure is defined by the entities, for example, companies, customers, patients, etc., seeking services from the items, using the need attributes. For the smooth performance of the service, the entities define the need attributes with corresponding requirement measures and corresponding importance measures.

Also, as used herein, requirement measure is a Boolean value associated with a need attribute representing that the item attribute amount measure of the item attribute is required to be equal to the need attribute amount measure of the need attribute, where the need attribute is the same as the item attribute. The requirement measure is associated with need attributes that are basic and mandatory for a need, for example, licenses and certifications such as a medical license for a physician to treat a patient, a certified public accountant (CPA) for auditing accounts of a company, etc.

Also, as used herein, importance measure is a quantized value representing a degree to which presence of a need attribute in the first attribute list is required for a need. That is, the importance measure is the weightage associated with an item attribute for the need. The importance measure is a numerical value between 0 and 1, both inclusive. A need attribute with an importance measure of 0.1 is considered to be barely important for the need, and a need attribute with an importance measure of 0.9 is considered to be very important.

In the method disclosed herein, the need matching system receives 101 the first attribute list comprising the item attributes in the item profiles and the second attribute list comprising the need attributes required for a need from the attribute list database. The first attribute list comprises first tuples. Each of the first tuples comprises one of the item attributes, the item attribute amount measure corresponding to the item attribute, and the credibility measure indicating the credibility of the item attribute amount measure. The second attribute list comprises second tuples. Each of the second tuples comprises one of the need attributes, the requirement measure, the importance measure, and the need attribute amount measure associated with the need attribute.

The need matching system creates 102 a unique attribute list comprising unique item attributes from the first attribute list, a merged attribute amount measure corresponding to each of the unique item attributes, and a merged credibility measure indicating the credibility of the merged attribute amount measure by performing merging actions on the first tuples in the first attribute list. In performing the merging actions, the need matching system computes the merged attribute amount measure and the merged credibility measure corresponding to each of the unique item attributes using the item attribute amount measure and the credibility measure of each of the item attributes of the first attribute list as disclosed in the detailed description of FIGS. 12A-12N. As used herein, unique item attributes refers to item attributes with multiple occurrences in the first attribute list that are merged to a single occurrence. Also, as used herein, a merged attribute amount measure refers to a combined value of the item attribute amount measures corresponding to the multiple occurrences of the item attributes in the first attribute list. Also, as used herein, a merged credibility measure refers to a combined value of the credibility measures corresponding to the multiple occurrences of the item attributes in the first attribute list.

The need matching system merges multiple reports or occurrences of an item attribute where the reports are of mixed credibility measures. That is, the item attributes in the first attribute list have item attribute amount measures provided by reviewers of varied credibility and thus, the item attribute amount measures have mixed credibility measures. The need matching system determines a merged credibility measure of 0.13 for two reports of low credibility measures of 0.9 and two reports of high credibility measures of 0.1 indicating the reports with the low credibility measures have minimal impact on the merged credibility measure, instead of averaging out the credibility measures of 0.9 and 0.1 to a merged credibility measure of 0.5. Consider an example where 15 reports of an item attribute amount measure of 0.80 of an item attribute such as the hypertext preprocessor (PHP) programming language with a credibility measure of 0.50 are present in the first attribute list and 2 reports of another item attribute with the same item attribute amount measure and the same credibility measure are also present in the first attribute list. The need matching system determines, in the above example, that the 15 reports of the item attribute amount measure of 0.80 for the PHP programming language with the credibility measure of 0.50 has a higher merged credibility measure than the 2 reports of another item attribute with the same item attribute amount measure and credibility measure.

The need matching system creates 103 a matched attribute list by matching the unique item attributes of the created unique attribute list with the need attributes of the second attribute list on combining the created unique attribute list with the second attribute list as disclosed in the detailed description of FIGS. 12A-12N. The need matching system generates 104 an attribute match score for each of the need attributes in the created matched attribute list on matching the unique item attributes with the need attributes using the requirement measure, the importance measure, the need attribute amount measure, the merged attribute amount measure, and the merged credibility measure as disclosed in the detailed description of FIGS. 12A-12N. For the generation of the attribute match score for each of the need attributes, the need matching system determines deviations in the merged attribute amount measure and the need attribute amount measure using an amount measure deviation lookup table.

Furthermore, the need matching system generates 105 a need match score defining the degree of match between the item profiles and the need profiles by processing the generated attribute match score for each of the need attributes with the importance measure of each of the need attributes in the second attribute list. The need matching system also determines whether a need attribute is absent in the created unique attribute list and assigns default values to the merged attribute amount measure and the merged credibility measure corresponding to the need attribute in the matched attribute list as disclosed in the detailed description of FIGS. 12A-12N.

The need matching system has multiple areas of applications. In an embodiment, the need matching system is used in an employment process. The need matching system can be used for matching of job seekers to jobs in the employment process. In an embodiment, the need matching system is used for matching customers with certain item attributes to a business. In an embodiment, the need matching system is used for matching diners with certain item attributes to a restaurant. In an embodiment, the need matching system is used for matching lawyers with item attributes, for example, stock option plan creation, deposition taking, responsiveness, communication, etc., to entities such as companies. The reviewers need not read text heavy opinions and types of reviews comprising ratings in the form of stars, provided on websites, for example, www.yelp.com of Yelp Inc., www.amazon.com of Amazon.com, Inc., etc., to determine a matching need and a matching item respectively. The reviewers can arrive at, for example, a purchasing decision, a hiring decision, an employment decision, etc., at the earliest using the need matching system. The need matching system gauges the items across different item attributes with uniformity. The output of the need matching system, the single numerical score corresponding to the item profiles and the need profiles can be used for advanced computing analysis such as machine learning for further analysis.

FIG. 2 exemplarily illustrates a method for generating a need match score implemented by the need matching system 200 on comparison of the item attributes with varying ratings of varying credibility with the need attributes of varying importance. As exemplarily illustrated in FIG. 2, the need matching system 200 comprises a merge module 201, a match module 202, and a score module 203. The merge module 201 performs merging actions on the item attributes in a list of attributes present, that is, the first attribute list. The merge module 201 returns a list of unique merged attributes present, that is, the unique attribute list. The need matching system 200 invokes the match module 202 with the list of unique merged attributes present and a list of attributes needed, that is, the second attribute list. The match module 202 combines the list of unique merged attributes present and the list of attributes needed and returns a list of matched attribute entries, that is, the matched attribute list. The match module 202 comprises an attribute entry match module 221 exemplarily illustrated in FIG. 7, for receiving the list of matched attribute entries. The attribute entry match module 221 returns a list of matched attributes. The need matching system 200 invokes the score module 203 with the list of matched attributes. The score module 203 returns a single numerical match score, that is, the need match score.

FIG. 3 exemplarily illustrates a flow diagram comprising the steps performed by the merge module 201 of the need matching system 200 exemplarily illustrated in FIG. 2, for creating the list of unique merged attributes present, that is, the unique attribute list comprising the unique item attributes, that is, the attributes present, a corresponding merged attribute amount measure, and a corresponding merged credibility measure. The merge module 201 combines multiple entries, that is, multiple occurrences of the item attributes in the list of attributes present into one entry per item attribute in the list of unique merged attributes present with a combined amount present measure, that is, the merged amount measure, and a combined credibility measure, that is, the merged credibility measure. The need matching system 200 invokes the merge module 201 with a list of attributes present. The merging module 201 sorts 204 the entries in the list of attributes present by the item attributes and then splits 205 the list of attributes present into N sub-lists of attributes present, where each sub-list of attributes present contains entries for a common attribute, that is, for a single item attribute. The merge module 201 comprises a combine module 207 for generating a single merged attribute, that is, a unique item attribute from each of the N sub-lists of attributes present 206 as disclosed in the detailed description of FIG. 4. The merge module 201 assembles 208 the unique item attribute from each of the N sub-lists of attributes present 206 into a new list of unique merged attributes present. A list of the unique merged attributes present, that is, the unique attribute list is the output of the merge module 201.

FIG. 4 exemplarily illustrates a flow diagram comprising the steps performed by the combine module 207 exemplarily illustrated in FIG. 3, of the need matching system 200 exemplarily illustrated in FIG. 2, for combining multiple occurrences of an item attribute in the first attribute list, that is, the list of attributes present into a single merged attribute, that is, a unique item attribute with a corresponding merged amount measure and a corresponding merged credibility measure. The need matching system 200 invokes the combine module 207 with a sub-list of attributes present 206 as disclosed in the detailed description of FIG. 3, such that each entry in the sub-list of attributes present 206 is for the same item attribute. In an embodiment, the N sub-list of attributes present 206 comprises the item attributes extracted by the operational system of the entity from different item profiles, for example, resumes and reviews of job seekers. The combine module 207 comprises a compute attribute values module 210 and an attribute combiner 212. The compute attribute values module 210 computes attribute values, that is, a weighted attribute amount measure and a weighted credibility measure for each item attribute in the N sub-lists of attributes present 209 as disclosed in the detailed description of FIG. 5. The compute attribute values module 210 adds values for the weighted attribute amount measure and the weighted credibility measure to each item attribute in the N sub-lists of attributes present 206 to create tuples in the N sub-lists of attributes present 206 as disclosed in the detailed description of FIG. 6. The combine module 207 assembles 211 the single sub-list of attributes present 206 comprising the item attributes with corresponding computed attribute values into a list. The attribute combiner 212 returns a single merged or combined attribute, that is, a unique item attribute on combining the enhanced attributes present tuples, that is, the tuples with the item attributes and corresponding weighted attribute amount measures and corresponding weighted credibility measures as disclosed in the detailed description of FIG. 6.

FIG. 5 exemplarily illustrates a flow diagram comprising the steps performed by the need matching system 200 exemplarily illustrated in FIG. 2, for computing attribute values, that is, a weighted attribute amount measure and a weighted credibility measure for each item attribute in the N sub-lists of attributes present 206 exemplarily illustrated in FIG. 3. The compute attribute values module 210 computes 213 a weighted amount present measure as attribute amount measure*credibility measure of the item attribute. The compute attribute values module 210 computes 214 a weighted credibility measure as credibility measure*credibility measure of the item attribute. The compute attribute values module 210 returns an item attribute in the sub-list of attributes present 206 with the computed values of the weighted amount present measure and the weighted credibility measure.

In the computation of the weighted amount present measures and the weighted credibility measures of the item attributes in the N sub-list of attributes present 206, the credibility measures affect the weightage provided to the item attribute amount measures of the item attributes in the N sub-list of attributes present 206. The credibility measures also affect the weightage provided to the credibility measures. A sum of the weighted credibility measures of an item attribute in a sub-list of attributes present 206 is used to calculate a credibility adjustment, that is, a credibility bump that is added to an unadjusted credibility measure to generate a merged credibility measure of the item attribute as disclosed in the detailed description of FIG. 6.

FIG. 6 exemplarily illustrates a flow diagram comprising the steps performed by the need matching system 200 exemplarily illustrated in FIG. 2, for generating a unique item attribute with a corresponding merged attribute amount measure and a corresponding merged credibility measure. The attribute combiner 212 exemplarily illustrated in FIG. 4, receives a sub-list of attributes present 206 exemplarily illustrated in FIG. 3, with the computed values of the weighted amount present measure and the weighted credibility measure and creates a single combined attribute, that is, a unique item attribute. The need matching system 200 invokes the attribute combiner 212 with a sub-list of attributes present 206 with computed values such that all entries in the sub-list of attributes present 206 are for the same item attribute. The attribute combiner 212 computes 215 a combined amount present measure, that is, the merged attribute amount measure as Sum(weighted amount present measure)/Sum(credibility measure). The attribute combiner 212 computes 216 a combined unadjusted credibility measure as Sum(weighted credibility measure)/Sum(credibility measure). The attribute combiner 212 computes 217 a credibility bump as (Sum(weighted credibility measure)*coeff_credbump)coeff_credbump, where the coefficient coeff_credbump is a predefined constant. In an embodiment, the credibility bump is computed by a lookup of the Sum(weighted credibility measure), for example, as in VLOOKUP in Excel of Microsoft Corporation. The attribute combiner 212 computes 218 a combined credibility measure, that is, the merged credibility measure, as (combined unadjusted credibility measure+credibility bump) that is adjusted to have a minimum value of 0 and a maximum value of 1. The attribute combiner 212 creates 219 a combined attribute tuple, that is, a tuple in the unique attribute list, comprising the unique item attribute being the attribute from the sub-list of the attributes present with the computed combined amount present measure and the computed combined credibility measure. The attribute combiner 212 returns a single merged attribute or a combined attribute, that is, the unique item attribute. The merge module 201 assembles 208 the unique item attribute from each of the N sub-lists of attributes present 206 into the unique attribute list, that is, the list of unique merged attributes present as disclosed in the detailed description of FIG. 3.

FIG. 7 exemplarily illustrates a flow diagram comprising the steps performed by the need matching system 200 exemplarily illustrated in FIG. 2, for combining the unique attribute list, that is, the list of unique merged attributes present and the second attribute list, that is, the list of attributes needed to return a list of matched attributes, that is, the matched attribute list. For each unique attribute in the list of unique merged attributes needed 220, the need matching system 200 invokes the attribute entry match module 221 with the list of unique merged attributes present and the list of attributes needed. The attribute entry match module 221 returns a single matched attribute that is assembled 222 into the list of matched attributes, that is, the matched attribute list as disclosed in the detailed description of FIG. 8.

FIG. 8 exemplarily illustrates a flow diagram comprising the steps performed by the need matching system 200 exemplarily illustrated in FIG. 2, for generating a single matched attribute from an attribute needed, that is, the need attribute contained in the list of attributes needed, that is, the second attribute list and a list of unique merged attributes present, that is, the unique attribute list. The attribute entry match module 221 exemplarily illustrated in FIG. 7, examines 223 whether the list of unique merged attributes present contains the attribute needed, that is, the need attribute. If the need attribute is present in the list of unique merged attributes present, the attribute entry match module 221 passes the unique item attribute that is the same as the need attribute as an attribute_present to a create matched attribute module 226. If the need attribute is absent in the list of unique merged attributes present, the attribute entry match module 221 fetches 225 the need attribute from a system attribute table 224, that is, the attribute list database and passes the fetched need attribute to the create matched attribute module 226 as an attribute_present. The create matched attribute module 226 accepts the attribute_present and the need attribute and creates a matched attribute tuple comprising a need attribute amount measure, an importance measure, and a requirement measure of the need attribute and a merged attribute amount measure and a merged credibility measure of the attribute_present.

FIG. 9 exemplarily illustrates a flow diagram comprising the steps performed by the score module 203 of the need matching system 200 exemplarily illustrated in FIG. 2, for generating a single numerical match score, that is, the need match score from a list of matched attributes, that is, the matched attribute list. The need matching system 200 invokes the score module 203 exemplarily illustrated in FIG. 2, with the list of matched attributes as disclosed in the detailed description of FIG. 2. In step 227, each matched attribute, that is, a unique item attribute matched with a need attribute from the matched attribute list is passed to a need match score generation module 228 that adds to each matched attribute, additional values of a delta and a match score and generates a scored matched attribute. For example. the need match score generation module 228 receives the input comprising each matched attribute, that is, the unique item attribute matched with the need attribute from the matched attribute list and technically processes the input. The the need match score generation module 228 using the processor 1503 computes the additional values of the delta and the match score, and transforms the input into the scored matched attribute by an algorithm in the need matching system 200 to generates the scored matched attribute. The score module 203 examines 229 whether the matched attribute has an ISREQ value, that is, a requirement measure of TRUE in the second attribute list, and whether a deviation, the delta, is less than zero. If the matched attribute has an ISREQ value of TRUE and if the delta is less than zero, the score module 203 returns a final numerical score, that is, the need match score of zero regardless of any other processing. If the matched attribute does not have an ISREQ value of TRUE and if the delta is more than zero, the score module 203 assembles 230 the scored matched attributes, that is, the matched attributes in the matched attribute list with associated attribute match scores into a list and passes the list to a final score module 231 that returns the single numerical match score.

FIG. 10 exemplarily illustrates a flow diagram comprising the steps performed by the need matching system 200 exemplarily illustrated in FIG. 2, for generating a scored match attribute, that is, a need attribute in the matched attribute list with an associated attribute match score. The match score module 228 exemplarily illustrated in FIG. 9, receives the matched attribute, that is, the need attribute matching with an item attribute in the matched attribute list. The match score module 228 computes 232 the delta as difference in the merged attribute amount measure, Amount_Present, and need attribute amount measure, Amount_Needed. That is, the match score module 228 determines deviation in the merged attribute amount measure and the need attribute amount measure as disclosed in the detailed description of FIG. 1. The match score module 228 computes 233 an over/under adjustment using a lookup of (delta/Amount_Needed) against an amount measure deviation lookup table exemplarily illustrated in FIG. 12N, that returns a numerical value for different data ranges of the value of the (delta/Amount_Needed). The match score module 228 further computes 234 an attribute match score as (importance measure*credibility measure*over/under adjustment) for each matched attribute. The match score module 228 adds additional values of delta and the attribute match score to each of the matched attributes and generates scored matched attributes as disclosed in the detailed description of FIG. 9.

FIG. 11 exemplarily illustrates a flow diagram comprising the steps performed by the need matching system 200 exemplarily illustrated in FIG. 2, for generating a need match score, that is, a single numerical match score for the scored matched attributes. The need matching system 200 invokes a final score module 231 exemplarily illustrated in FIG. 9, with a list of scored matched attributes, that is, the matched attributes in the matched attribute list with associated attribute match scores. The final score module 231 calculates 235 a single numerical match score as Sum(attribute match score)/Sum(importance measure). The single numerical match score determines the degree of match between the need attributes and the item attributes.

In an embodiment, the attribute list database is a relational database. The amount measure deviation lookup table and the predefined attribute table 224 exemplarily illustrated in FIG. 8, in an embodiment, form a part of a relational database. The amount measure deviation lookup table and the predefined attribute table 224, in an embodiment, are flat files. The attribute list database, in an embodiment, is a persistent data store.

FIGS. 12A-12N exemplarily illustrate tabular representations of computations associated with item attributes and need attributes for determining a degree of match between item profiles with the item attributes with varying ratings of varying credibility and need profiles with the need attributes of varying importance. FIG. 12A exemplarily illustrates a first attribute list comprising item attributes, for example, MS Word, Excel, confidence, data mining, integrity, hypertext preprocessor (PHP) programming language, etc., extracted from item profiles, for example, resumes and reviews of the job seekers. The item attributes, for example, confidence, integrity, etc., are core traits, and the item attributes, for example, MS Word, PHP programming language, data mining, etc., are domains of expertise of the job seekers. As exemplarily illustrated in FIG. 12A, the first attribute list comprises multiple occurrences of the item attributes in random with corresponding attribute amount measures and corresponding credibility measures. The need matching system 200 receives the first attribute list exemplarily illustrated in FIG. 12A, comprising the item attributes from an attribute list database. The first attribute list comprises first tuples and each of the first tuples comprises an item attribute, an item attribute amount measure corresponding to the item attribute, and a credibility measure indicating credibility of the item attribute amount measure. As exemplarily illustrated in FIG. 12A, a first tuple in the first attribute list comprises an item attribute, for example, CONFIDENCE, the item attribute amount measure, that is, an amount present measure of 1.0, and a credibility measure of 0.50. Another first tuple in the first attribute list comprises EXCEL as an item attribute with a corresponding amount present measure of 0.90 and a corresponding credibility measure of 0.40. The first attribute list comprises multiple first tuples comprising MSWORD as an item attribute with corresponding amount present measures and corresponding credibility measures.

FIG. 12B exemplarily illustrates a second attribute list comprising need attributes required for a need. The second attribute list comprises second tuples and each of the second tuples comprises a need attribute, a need attribute amount measure corresponding to the need attribute, a requirement measure, and an importance measure associated with the need attribute. As exemplarily illustrated in FIG. 12B, a second tuple in the second attribute list comprises a need attribute, for example, MSWORD, a requirement measurement, that is, ISREQ value of NULL, an importance measure of 0.8, and a need attribute amount measure, that is, an amount needed measure of 0.20. Another second tuple comprises, for example, EXCEL as a need attribute with a corresponding requirement measure of 1, an importance measure of 0.30, and an amount needed measure of 0.50. The need matching system 200 receives the second attribute list exemplarily illustrated in FIG. 12B, from the attribute list database.

FIG. 12C exemplarily illustrates a unique attribute list created from the first attribute list exemplarily illustrated in FIG. 12A, by the need matching system 200. The need matching system 200 performs merging actions, that is, splitting and sorting of the first tuples of the first attribute list and computes a merged attribute amount measure, that is, the merged amount measure, and a merged credibility measure as exemplarily illustrated in FIGS. 12D-121. FIGS. 12D-121 exemplarily illustrate 6 sub-lists of the item attributes that are in the first attribute list exemplarily illustrated in FIG. 12A. As exemplarily illustrated in FIG. 12D, the merging module 201 of the need matching system 200 exemplarily illustrated in FIG. 2, creates a sub-list of the item attribute, CONFIDENCE, with a corresponding amount present measure, that is, the item attribute amount measure of 1.00 and the corresponding credibility measure of 0.50. The compute attribute values module 210 exemplarily illustrated in FIG. 4, determines a weighted amount present measure, that is, a weighted attribute amount measure as attribute amount measure*credibility measure=1.00*0.50=0.50, and a weighted credibility measure as credibility measure*credibility measure=0.50*0.50=0.25. The attribute combiner 212 exemplarily illustrated in FIG. 4, computes a merged amount measure, that is, a merged attribute amount measure as Sum(weighted amount present measure)/Sum(credibility measure). Since there is only one occurrence of the item attribute CONFIDENCE in the sub-list, the Sum(amount present measure)=1.00, the Sum(weighted amount present measure)=0.50, and the Sum(credibility measure)=0.50. The attribute combiner 212 computes the merged attribute amount measure as 0.50/0.50=1.00 and an unadjusted credibility measure as Sum(weighted credibility measure)/Sum(credibility measure)=0.25/0.5=0.5. The attribute combiner 212 computes the credibility bump as (Sum(weighted credibility measure)*coeff_credbump)coeff_credbump. The coeff_credbump is a constant preconfigured in the attribute combiner 212 as 0.1. The coeff_credbump defines the amount of credibility bump to provide to the N sub-lists. The coeff_credbump drives computations performed by the attribute combiner 212, affecting degree of adjustment to be made to the credibility measure. The attribute combiner 212 computes the credibility bump as (0.25*0.1)0.1=0.075. The attribute combiner 212 computes the merged credibility measure as (unadjusted credibility measure+credibility bump)=0.50.075=0.4250.43.

Similarly, the merging module 201 of the need matching system 200 exemplarily illustrated in FIG. 2, creates a sub-list of the item attribute, EXCEL, with corresponding amount present measures 0.90, 0.70, and 0.90 and credibility measures of 0.40, 0.80, and 0.50 as exemplarily illustrated in FIG. 12E. The compute attribute values module 210 determines a weighted amount present measure as attribute amount measure*credibility measure and a weighted credibility measure as credibility measure*credibility measure for each of the occurrences of the item attribute, EXCEL, in the sub-list. The weighted amount present measure is computed as 0.36, 0.56, and 0.45 and the weighted credibility measure is computed as 0.16, 0.64, and 0.25 respectively for the three occurrences of the item attribute, EXCEL, in the sub-list. The attribute combiner 212 computes a merged attribute amount measure as Sum(weighted amount present measure)/Sum(credibility measure). The Sum(weighted amount present measure)=1.37, Sum(credibility measure)=1.70, and Sum(weighted credibility measure)=1.05. The attribute combiner 212 computes the merged attribute amount measure as 1.37/1.7=0.8050.81 and the unadjusted credibility measure as Sum(weighted credibility measure)/Sum(credibility measure)=1.05/1.7=0.62. The attribute combiner 212 computes the credibility bump as (Sum(weighted credibility measure)*coeff_credbump)coeff_credbump with the coeff_credbump as 0.1. The attribute combiner 212 computes the credibility bump as (1.05*0.1)0.1=0.005. The attribute combiner 212 computes the merged credibility measure as (unadjusted credibility measure+credibility bump)=0.62+0.005=0.6250.62.

As exemplarily illustrated in FIG. 12F, a sub-list of 10 reports or occurrences of the item attribute, INTEGRITY, with corresponding amount present measures of 0.50 and corresponding credibility measures of 0.70 is created. The attribute combiner 212 computes a merged attribute amount measure and a merged credibility measure as disclosed in the detailed description of FIGS. 12D-12E, as 0.50 and 1.00 Similarly, in FIG. 12G, a sub-list of 2 reports of the item attribute, PHP, with corresponding amount present measures of 0.50 and credibility measures of 0.70 is created. The attribute combiner 212 computes a merged attribute amount measure and a merged credibility measure as disclosed in the detailed description of FIGS. 12D-12E, as 0.50 and 0.70. As exemplarily illustrated in FIGS. 12F-12G, the item attribute INTEGRITY with 10 reports of the attribute amount measure 0.50 has more merged credibility measure than 2 reports of the item attribute PHP with 2 reports of attribute amount measure 0.50. A credibility bump lowers credibility of few reports of low credibility measures and increases credibility of reports of large credibility measures. The credibility bump is between 0 and 1 and smaller values of credibility bump means more unadjusted credibility measure is needed to get a positive merged credibility measure. For a lower credibility measure, the number of occurrences of the item attribute in the sub-list, that is, rows needed to obtain a positive credibility bump is more for a coeff_credbump=0.1 For a credibility measure of 1.00, 1 report is sufficient to obtain a positive credibility bump. For a credibility measure of 0.8, 2 reports are sufficient to obtain a positive credibility bump. For a credibility measure of 0.6, 3 reports are sufficient to obtain a positive credibility bump. For a credibility measure of 0.4, 10 reports are sufficient to obtain a positive credibility bump. For a credibility measure of 0.2, more than 20 reports are sufficient to obtain a positive credibility bump. For a credibility measure of 0.1, 100 reports are sufficient to obtain a positive credibility bump. The merging module 201 of the need matching system 200 determines the merged attribute amount measure and the merged credibility measure for the remaining item attributes in the first attribute list, exemplarily illustrated in FIG. 12A, as exemplarily illustrated in FIGS. 12F-12I, and creates the unique attribute list as exemplarily illustrated in FIG. 12C.

FIG. 12J exemplarily illustrates a matched attribute list created by the need matching system 200 by matching the unique item attributes in the unique attribute list exemplarily illustrated in FIG. 12C, with the need attributes in the second attribute list exemplarily illustrated in FIG. 12B. The need attribute, DEPENDABILITY, in the second attribute list exemplarily illustrated in FIG. 12B, is absent in the unique attribute list exemplarily illustrated in FIG. 12C. The attribute entry match module 221 exemplarily illustrated in FIG. 7, fetches the need attribute, that is, the attribute needed, from the predefined attribute table in the attribute list database 224 exemplarily illustrated in FIG. 8 and FIG. 12M, along with a corresponding default amount present measure and a default credibility measure. The attribute entry match module 221 inputs the amount present measure and the credibility measure as 0.5 and 0.25 respectively, from the predefined attribute table 224, that is, the attribute list database exemplarily illustrated in FIG. 12M. The need attributes and the item attributes in the predefined attribute table 224 comprise domains of expertise and core traits of the items. The core traits, as exemplarily illustrated in FIG. 12M, are indicated by an ISTRAIT flag. The processing of the item attribute amount measure and the credibility measure for a core trait by the need matching system 200 is the same as the processing of the item attribute amount measure and the credibility measure for a domain of expertise. The core traits have a default amount present measure and a default credibility measure as every item has a core trait to some degree. The item attribute amount measure and the credibility measure of the core traits are not limited to the default amount present measure and the default credibility measure in the predefined attribute table 224. For example, the need attribute writing attributes is presumed to be present to a default level in items for which there are no other indications apart from the item attribute amount measure and the credibility measure.

FIG. 12K exemplarily illustrates the matched attribute list exemplarily illustrated in FIG. 12J, comprising attribute match scores generated by the score generation module 203 of the need matching system 200 exemplarily illustrated in FIG. 2, on matching the unique item attributes in the unique attribute list exemplarily illustrated in FIG. 12C, with the need attributes in the second attribute list exemplarily illustrated in FIG. 12B. The need match score generation module 228, exemplarily illustrated in FIG. 15, adds to each matched attribute, additional values of delta and determines the attribute match score, that is, the row match score using an over/under adjustment. The over/under adjustment is a conventional lookup, for example, performed by a VLOOKUP function in MS Excel of Microsoft Corporation. The over/under adjustment is used for downgrading or penalizing matches with large differences between the unique item attributes and the need attributes. Consider an example of an oral surgeon with 100% dental attributes whose dental attributes are underutilized in a dental hygienist job since the dental hygienist job needs only 10% dental attributes. The oral surgeon may quickly leave the position of a dental hygienist if the oral surgeon finds another position using more of the dental attributes. The need match score generation module 228 fetches an overattributed adjustment from an amount measure deviation lookup table exemplarily illustrated in FIG. 12N, as 0.1 and the row match score is computed to be low, indicating the oral surgeon is not a match for a dental hygienist job. Consider another example of a dental hygienist with 10% dental attributes whose dental attributes are insufficient for a role of an oral surgeon since the role of oral surgeon needs only 100% dental attributes. If placed in the job of an oral surgeon, the dental hygienist may soon be dismissed due to the inability to perform the required job activities of the oral surgeon. The need match score generation module 228 fetches an underattributed adjustment from the amount measure deviation lookup table as 0.1 and the row match score is computed to be low, indicating the dental hygienist is not a match for the role of the oral surgeon. If the item attribute is close to the need attribute, over or under, the over/under adjustments are closer to 1 or equal to 1, making the row match score high between the item attribute and the need attribute as the importance measure of the need attribute and the credibility measure of the item attribute allow.

The need match score generation module 228 computes delta as difference in an attribute amount present measure and an attribute amount needed measure. As exemplarily illustrated in FIG. 12K, the delta for the matched attribute, DEPENDABILITY, is 0.500.90=0.40. The need match score generation module 228 determines an over/under adjustment using a lookup of (delta/attribute amount needed measure) against the amount measure deviation lookup table exemplarily illustrated in FIG. 12N. The value of (delta/attribute amount needed measure)=0.40/0.90=0.440.5. The corresponding over/under adjustment from the amount measure deviation lookup table is 0.6. The need match score generation module 228 computes the attribute match score as (importance measure*credibility measure*over/under adjustment)=0.90*0.25*0.60=0.1350.14 as exemplarily illustrated in FIG. 12K. Similarly, for the other matched attributes, the need match score generation module 228 computes the attribute match scores as 0.05, 0.09, and 0.12 for the matched attributes MSWORD, EXCEL, and CONFIDENCE respectively.

FIG. 12L exemplarily illustrates a tabular representation for generation of a need match score defining the degree of match between the item profiles and the need profiles by the final match score generation module 231 exemplarily illustrated in FIG. 9. The final match score generation module 231 calculates a single numerical match score, that is, the need match score, as Sum(attribute match score)/Sum(importance measure)=(0.05+0.09+0.12+0.14)/(0.8+0.3+0.4+0.9)=0.40/2.40=0.16720.17.

FIGS. 13A-13N exemplarily illustrate another embodiment of tabular representations of computations associated with item attributes and need attributes for determining a degree of match between item profiles with the item attributes with varying ratings of varying credibility and need profiles with the need attributes of varying importance. FIG. 13A exemplarily illustrates a first attribute list comprising item attributes, for example, MS Word, Excel, confidence, data mining, integrity, hypertext preprocessor (PHP) programming language, etc., extracted from item profiles, for example, resumes and reviews of the job seekers. The item attributes, for example, confidence, and integrity are core traits, and the item attributes, for example, MS Word, Excel, PHP programming language, and data mining are domains of expertise of the job seekers. As exemplarily illustrated in FIG. 12A, the first attribute list comprises multiple occurrences of the item attributes in random with corresponding attribute amount measures and corresponding credibility measures. The first attribute list comprises first tuples and each of the first tuples comprises an item attribute, an item attribute amount measure corresponding to the item attribute, and a credibility measure indicating credibility of the item attribute amount measure. As exemplarily illustrated in FIG. 13A, a first tuple in the first attribute list comprises an item attribute, for example, CONFIDENCE, the item attribute amount measure, that is, an amount present measure of 1.00, and a credibility measure of 0.50. Another first tuple in the first attribute list comprises DATA MINING as an item attribute with a corresponding amount present measure of 0.40 and a corresponding credibility measure of 0.40.

FIG. 13B exemplarily illustrates a second attribute list comprising need attributes required for a need. The second attribute list comprises second tuples and each of the second tuples comprises a need attribute, a need attribute amount measure corresponding to the need attribute, a requirement measure, and an importance measure associated with the need attribute. The second attribute list is similar to that of the second attribute list as exemplarily illustrated in the detailed description of FIG. 12B. As exemplarily illustrated in FIG. 13B, a second tuple in the second attribute list comprises a need attribute, for example, CONFIDENCE, a requirement measurement, that is, ISREQ value of NULL, an importance measure of 0.40, and an need attribute amount measure, that is, an amount needed measure of 0.70. Another second tuple comprises, for example, DEPENDABILITY as a need attribute with a corresponding requirement measure of 0, an importance measure of 0.90, and an amount needed measure of 0.90. The need matching system 200 receives the second attribute list exemplarily illustrated in FIG. 13B, from the attribute list database 224, as exemplarily illustrated in FIG. 15.

FIG. 13C exemplarily illustrates a unique attribute list created from the first attribute list exemplarily illustrated in FIG. 13A, by the need matching system 200. As exemplarily illustrated in FIG. 13C, the unique attribute list created from the first attribute list, for example, EXCEL, the item attribute amount measure, that is, an amount present measure of 0.81 and a credibility measure of 0.74. Another example of the unique attribute list created from the first attribute list, for PHP, the item attribute amount measure, that is, an amount present measure of 0.50 and a credibility measure of 0.77.

The need matching system 200 performs merging actions, that is, splitting and sorting of the first tuples of the first attribute list and computes a merged attribute amount measure, that is, the merged amount measure, and a merged credibility measure as exemplarily illustrated in FIGS. 13D-13I. FIGS. 13D-13I exemplarily illustrate 6 sub-lists of the item attributes that are in the first attribute list exemplarily illustrated in FIG. 13A. As exemplarily illustrated in FIG. 13D, the merging module 201 of the need matching system 200 exemplarily illustrated in FIG. 2, creates a sub-list of the item attribute, EXCEL, with a corresponding amount present measure, that is, the item attribute amount measure of 0.90, 0.70, and 0.90 and the corresponding credibility measures of 0.40, 0.80, and 0.50. The compute attribute values module 210 exemplarily illustrated in FIG. 4, determines a weighted amount present measure, that is, a weighted attribute amount measure as attribute amount measure*credibility measure and a weighted credibility measure as credibility measure*credibility measure for each of the occurrences of the item attribute, EXCEL, in the sub-list. The weighted amount present measure is computed as 0.36, 0.56, and 0.45 and the weighted credibility measure is computed as 0.16, 0.64, and 0.25 respectively for the 3 occurrences of the item attribute, EXCEL, in the sublist. The attribute combiner 212 exemplarily illustrated in FIG. 4, computes a merged amount measure, that is, a merged attribute amount measure as Sum(weighted amount present measure)/Sum(credibility measure). Since there are three occurrences of the item attribute EXCEL in the sub-list, the Sum(weighted amount present measure)=1.37, the Sum(credibility measure)=1.70, and the Sum(weighted credibility measure)=1.05. The attribute combiner 212 computes the merged attribute amount measure as 1.37/1.70=0.810 and an unadjusted credibility measure as Sum(weighted credibility measure)/Sum(credibility measure)=1.05/1.70=0.62. The attribute combiner 212 computes the credibility bump as (Count(weighted credibility measure)1)*unadjusted credibility measure*coeff_credbump with the coeff_credbump as 0.1. The coeff_credbump defines the amount of credibility bump to provide to the N sub-lists. The coeff_credbump drives computations performed by the attribute combiner 212, affecting degree of adjustment to be made to the credibility measure. The attribute combiner 212 computes the credibility bump as (31)*0.62*0.1=0.124. The attribute combiner 212 computes the merged credibility measure as (unadjusted credibility measure+credibility bump)=0.62+0.124=0.7440.74. The merged attribute amount measure of 0.81 is different than 0.83 which is the simple average of the amount present measures of the item attribute, EXCEL.

Similarly, the merging module 201 of the need matching system 200 exemplarily illustrated in FIG. 2, creates a sub-list of the item attribute, PHP, with a corresponding amount present measures 0.50, and 0.50 and a corresponding credibility measures of 0.70, and 0.70 as exemplarily illustrated in FIG. 13E. The compute attribute values module 210 determines a weighted amount present measure as attribute amount measure*credibility measure and a weighted credibility measure as credibility measure*credibility measure for each of the occurrences of the item attribute, PHP, in the sub-list. The weighted amount present measure is computed as 0.35 and 0.35, and the weighted credibility measure is computed as 0.49 and 0.49, respectively for the two occurrences of the item attribute, PHP, in the sublist. The attribute combiner 212 computes a merged attribute amount measure as the Sum(weighted amount present measure)/Sum(credibility measure). The Sum(weighted amount present measure)=0.70, the Sum(credibility measure)=1.40, and the Sum(weighted credibility measure)=0.98. The attribute combiner 212 computes the merged attribute amount measure as 0.70/1.40=0.500 and the unadjusted credibility measure as the Sum(weighted credibility measure)/Sum(credibility measure)=0.98/1.40=0.70. The attribute combiner 212 computes the credibility bump as (Count(weighted credibility measure)1)*unadjusted credibility measure*coeff_credbump with the coeff_credbump as 0.1. The attribute combiner 212 computes the credibility bump as (21)*0.70*0.1=0.070. The attribute combiner 212 computes the merged credibility measure as (unadjusted credibility measure+credibility bump)=0.70+0.070=0.77.

Similarly, the merging module 201 of the need matching system 200 exemplarily illustrated in FIG. 2, creates a sub-list of the item attribute, MSWORD, with a corresponding amount present measures 0.70, 1.00, and 0.50 and a corresponding credibility measures of 0.80, 0.10, and 0.60 as exemplarily illustrated in FIG. 13F. The compute attribute values module 210 determines a weighted amount present measure as attribute amount measure*credibility measure and a weighted credibility measure as credibility measure*credibility measure for each of the occurrences of the item attribute, MSWORD, in the sub-list. The weighted amount present measure is computed as 0.56, 0.10, and 0.30 and the weighted credibility measure is computed as 0.64, 0.01, and 0.36 respectively for the 3 occurrences of the item attribute, MSWORD, in the sublist. The attribute combiner 212 computes a merged attribute amount measure as the Sum(weighted amount present measure)/Sum(credibility measure). The Sum(weighted amount present measure)=0.96, the Sum(credibility measure)=1.50, and the Sum(weighted credibility measure)=1.01. The attribute combiner 212 computes the merged attribute amount measure as 0.96/1.50=0.640 and the unadjusted credibility measure as the Sum(weighted credibility measure)/Sum(credibility measure)=1.01/1.50=0.67. The attribute combiner 212 computes the credibility bump as (Count(weighted credibility measure)1)*unadjusted credibility measure*coeff_credbump with the coeff_credbump as 0.1. The attribute combiner 212 computes the credibility bump as (31)*0.67*0.1=0.134. The attribute combiner 212 computes the merged credibility measure as (unadjusted credibility measure+credibility bump)=0.67+0.134=0.8040.80. The merged attribute amount measure of 0.64 is different than 0.73 which is the simple average of the amount present measures.

Similarly, the merging module 201 of the need matching system 200 exemplarily illustrated in FIG. 2, creates a sub-list of the item attribute, DATA MINING, with a corresponding amount present measures 0.30, and 0.40 and a corresponding credibility measures of 0.90, and 0.40 as exemplarily illustrated in FIG. 13G. The compute attribute values module 210 determines a weighted amount present measure as attribute amount measure*credibility measure and a weighted credibility measure as credibility measure*credibility measure for each of the occurrences of the item attribute, DATA MINING, in the sub-list. The weighted amount present measure is computed as 0.27, and 0.16 and the weighted credibility measure is computed as 0.81, and 0.16 respectively for the 2 occurrences of the item attribute, DATA MINING, in the sublist. The attribute combiner 212 computes a merged attribute amount measure as the Sum(weighted amount present measure)/Sum(credibility measure). The Sum(weighted amount present measure)=0.43, the Sum(credibility measure)=1.30, and the Sum(weighted credibility measure)=0.97. The attribute combiner 212 computes the merged attribute amount measure as 0.43/1.30=0.330 and the unadjusted credibility measure as the Sum(weighted credibility measure)/Sum(credibility measure)=0.97/1.30=0.75. The attribute combiner 212 computes the credibility bump as (Count(weighted credibility measure)1)*unadjusted credibility measure*coeff_credbump with the coeff_credbump as 0.1. The attribute combiner 212 computes the credibility bump as (21)*0.75*0.1=0.075. The attribute combiner 212 computes the merged credibility measure as (unadjusted credibility measure+credibility bump)=0.75+0.075=0.8250.83. The merged attribute amount measure of 0.33 is different than 0.35 which is the simple average of the amount present measures.

Similarly, the merging module 201 of the need matching system 200 exemplarily illustrated in FIG. 2, creates a sub-list of the item attribute, CONFIDENCE, with a corresponding amount present measure 1.00 and a corresponding credibility measure of 0.50 as exemplarily illustrated in FIG. 13H. The compute attribute values module 210 determines a weighted amount present measure as attribute amount measure*credibility measure and a weighted credibility measure as credibility measure*credibility measure for each of the occurrences of the item attribute, CONFIDENCE, in the sub-list. The weighted amount present measure is computed as 0.50 and the weighted credibility measure is computed as 0.25, respectively for only one occurrence of the item attribute, CONFIDENCE, in the sublist. The attribute combiner 212 computes a merged attribute amount measure as the Sum(weighted amount present measure)/Sum(credibility measure). The Sum(weighted amount present measure)=0.50, the Sum(credibility measure)=0.50, and the Sum(weighted credibility measure)=0.25. The attribute combiner 212 computes the merged attribute amount measure as 0.50/0.50=1.000 and the unadjusted credibility measure as the Sum(weighted credibility measure)/Sum(credibility measure)=0.25/0.50=0.50. The attribute combiner 212 computes the credibility bump as (Count(weighted credibility measure)1)*unadjusted credibility measure*coeff_credbump with the coeff_credbump as 0.1. The attribute combiner 212 computes the credibility bump as (11)*0.50*0.1=0.000. The attribute combiner 212 computes the merged credibility measure as (unadjusted credibility measure+credibility bump)=0.50+0.000=0.50.

Similarly, the merging module 201 of the need matching system 200 exemplarily illustrated in FIG. 2, creates a sub-list of the item attribute, INTEGRITY, with a corresponding amount present measures 0.50, 0.50, 0.50, 0.50, 0.50, 0.50, 0.50, 0.50, 0.50, and 0.50 and a corresponding credibility measures of 0.70, 0.70, 0.70, 0.70, 0.70, 0.70, 0.70, 0.70, 0.70, and 0.70 as exemplarily illustrated in FIG. 131. The compute attribute values module 210 determines a weighted amount present measure as attribute amount measure*credibility measure and a weighted credibility measure as credibility measure*credibility measure for each of the occurrences of the item attribute, INTEGRITY, in the sub-list. The weighted amount present measure is computed as 0.35, 0.35, 0.35, 0.35, 0.35, 0.35, 0.35, 0.35, 0.35, and 0.35 and the weighted credibility measure is computed as 0.49, 0.49, 0.49, 0.49, 0.49, 0.49, 0.49, 0.49, 0.49, and 0.49 respectively for the ten occurrences of the item attribute, INTEGRITY, in the sublist.

The attribute combiner 212 computes the merged credibility measure as (unadjusted credibility measure+credibility bump)=0.70+0.630=1.33. The merged credibility measure is adjusted to have a maximum value of 1.

FIG. 13J exemplarily illustrates a matched attribute list created by the need matching system 200 by matching the unique item attributes in the unique attribute list exemplarily illustrated in FIG. 13C, with the need attributes in the second attribute list exemplarily illustrated in FIG. 13B. The need attribute, DEPENDABILITY, in the second attribute list exemplarily illustrated in FIG. 13B, is absent in the unique attribute list exemplarily illustrated in FIG. 13C. The attribute entry matching module 221 creates an attribute present entry with the amount present measure and the credibility measure as 0.64 and 0.8 respectively for MSWORD, from the predefined attribute table, that is, the attribute list database 224, as exemplarily illustrated in FIG. 13M. Similarly, the corresponding amount present measure and the corresponding credibility measure for EXCEL are 0.81 and 0.74 respectively as exemplarily illustrated in FIG. 13J.

FIG. 13K exemplarily illustrates the matched attribute list exemplarily illustrated in FIG. 13J, comprising attribute match scores generated by the score generation module 203 of the need matching system 200 exemplarily illustrated in FIG. 2, on matching the unique item attributes in the unique attribute list exemplarily illustrated in FIG. 13C, with the need attributes in the second attribute list exemplarily illustrated in FIG. 13B. The need match score generation module 228, exemplarily illustrated in FIG. 9, computes delta as difference in an attribute amount present measure and a attribute amount needed measure. As exemplarily illustrated in FIG. 13K, the delta for the matched attribute, MSWORD, is 0.640.20=0.44. The need match score generation module 228 determines an over/under adjustment using a lookup of (delta/attribute amount needed measure) against the amount measure deviation lookup table exemplarily illustrated in FIG. 13N. The value of (delta/attribute amount needed measure)=0.44/0.20=2.20. The corresponding over/under adjustment from the amount measure deviation lookup table is 0.10. The need match score generation module 228 computes the attribute match score as (importance measure* credibility measure* over/under adjustment)=0.80*0.80*0.10=0.0640.06 as exemplarily illustrated in FIG. 13K. Similarly, for the other matched attributes, the need match score generation module 228 computes the attribute match scores as 0.09, 0.12, and 0.16 for the matched attributes EXCEL, CONFIDENCE, and DEPENDABILITY, respectively.

FIG. 13L exemplarily illustrates a tabular representation for generation of an need match score defining the degree of match between the item profiles and the need profiles by the final match score generation module 231 exemplarily illustrated in FIG. 9. The final match score generation module 231 calculates a single numerical match score, that is, the need match score, as the Sum(attribute match score)/Sum(importance measure)=(0.06+0.09+0.12+0.16)/(0.80+0.30+0.40+0.90)=0.43/2.40=0.17960.18. The single numerical match score of 0.180 is different than 0.108 which is the simple average of the attribute match score without using importance as a weight.

FIG. 13M exemplarily illustrates a tabular representation of the default amount preset measure and the default credibility measure. For example, for the item attribute of CONFIDENCE, if the isTrait representation is TRUE, the default amount measure is 0.5 and the corresponding credibility measure is 0.3. For the item attribute of PHP, if the isTrait representation is FALSE, the default amount measure and the corresponding credibility measure are 0.

FIGS. 14A-14N exemplarily illustrate another embodiment of tabular representations of computations associated with item attributes and need attributes for determining a degree of match between item profiles with the item attributes of varying credibility and needs with the need attributes of varying importance. FIG. 14A exemplarily illustrates a first attribute list comprising item attributes, for example, MS Word, Excel, confidence, and dependability, extracted from item profiles, for example, resumes and reviews of the job seekers. As exemplarily illustrated in FIG. 14A, the first attribute list comprises multiple occurrences of the item attributes in random with corresponding attribute amount measures and corresponding credibility measures. The need matching system 200 receives the first attribute list exemplarily illustrated in FIG. 12A, FIG. 13A, and FIG. 14A comprising the item attributes from an attribute list database 224. The first attribute list comprises first tuples and each of the first tuples comprises an item attribute, an item attribute amount measure corresponding to the item attribute, and a credibility measure indicating credibility of the item attribute amount measure as exemplarily illustrated in the detailed description of FIG. 12A, FIG. 13A, and FIG. 14A. As exemplarily illustrated in FIG. 14A, a first tuple in the first attribute list comprises an item attribute, for example, EXCEL, the item attribute amount measure, that is, an amount present measure of 0.8, and a credibility measure of 0.8. Another first tuple in the first attribute list comprises MSWORD as an item attribute with a corresponding amount present measure of 0.8 and a corresponding credibility measure of 0.1.

FIG. 14B exemplarily illustrates a second attribute list comprising need attributes required for a need. The second attribute list comprises second tuples and each of the second tuples comprises an need attribute, an need attribute amount measure corresponding to the need attribute, a requirement measure, and an importance measure associated with the need attribute. The second attribute list is similar to that of the second attribute list as exemplarily illustrated in the detailed description of FIG. 12B and FIG. 13B. As exemplarily illustrated in FIG. 14B, a second tuple in the second attribute list comprises an need attribute, for example, MSWORD, a requirement measurement, that is, ISREQ value of NULL, an importance measure of 0.8, and an need attribute amount measure, that is, an amount needed measure of 0.20. Another second tuple comprises, for example, EXCEL as an need attribute with a corresponding requirement measure of 1, an importance measure of 0.30, and an amount needed measure of 0.50. The need matching system 200 receives the second attribute list exemplarily illustrated in FIG. 12B, FIG. 13B, and FIG. 14B from the attribute list database 224.

FIG. 14C exemplarily illustrates a unique attribute list created from the first attribute list exemplarily illustrated in FIG. 14A, by the need matching system 200. As exemplarily illustrated in FIG. 14C, the unique attribute list created from the first attribute list, for example, EXCEL, the item attribute amount measure, that is, an amount present measure of 0.68 and a credibility measure of 1. Another example of the unique attribute list created from the first attribute list, for MSWORD, the item attribute amount measure, that is, an amount present measure of 0.37 and a credibility measure of 1.

The need matching system 200 performs merging actions, that is, splitting and sorting of the first tuples of the first attribute list and computes a merged attribute amount measure, that is, the merged amount measure, and a merged credibility measure as exemplarily illustrated in FIGS. 14D-14G. FIGS. 14D-14G exemplarily illustrate 4 sub-lists of the item attributes that are in the first attribute list exemplarily illustrated in FIG. 14A. As exemplarily illustrated in FIG. 14D, the merging module 201 of the need matching system 200 exemplarily illustrated in FIG. 2, creates a sub-list of the item attribute, EXCEL, with a corresponding amount present measures 0.80, 0.80, 0.80, 0.80, 0.60, 0.60, 0.60, 0.60, 0.20, and 0.20 and a corresponding credibility measures of 0.80, 0.80, 0.80, 0.80, 0.80, 0.80, 0.80, 0.80, 0.10, and 0.10 as exemplarily illustrated in FIG. 14D. The compute attribute values module 210 determines a weighted amount present measure as attribute amount measure*credibility measure and a weighted credibility measure as credibility measure*credibility measure for each of the occurrences of the item attribute, EXCEL, in the sub-list. The weighted amount present measure is computed as 0.64, 0.64, 0.64, 0.64, 0.48, 0.48, 0.48, 0.48, 0.02, and 0.02 and the weighted credibility measure is computed as 0.64, 0.64, 0.64, 0.64, 0.64, 0.64, 0.64, 0.64, 0.01, and 0.01 respectively for the 10 occurrences of the item attribute, EXCEL, in the sublist. The attribute combiner 212 computes a merged attribute amount measure as the Sum(weighted amount present measure)/Sum(credibility measure). The Sum(weighted amount present measure)=4.52, the Sum(credibility measure)=6.60, and the Sum(weighted credibility measure)=5.14. The attribute combiner 212 computes the merged attribute amount measure as 4.52/6.60=0.680 and the unadjusted credibility measure as the Sum(weighted credibility measure)/Sum(credibility measure)=5.14/6.60=0.78. The attribute combiner 212 computes the credibility bump as (Count(weighted credibility measure)1)*unadjusted credibility measure*coeff_credbump with the coeff_credbump as 0.1. The coeff_credbump defines the amount of credibility bump to provide to the N sub-lists. The coeff_credbump drives computations performed by the attribute combiner 212, affecting degree of adjustment to be made to the credibility measure. The attribute combiner 212 computes the credibility bump as (101)*0.78*0.1=0.702. The attribute combiner 212 computes the merged credibility measure as (unadjusted credibility measure+credibility bump)=0.78+0.702=1.4821.48. The merged credibility measure is adjusted to have a maximum value of 1. The merged attribute amount measure of 0.68 is different than 0.60 which is the simple average of the amount present measures.

FIG. 14H exemplarily illustrates a matched attribute list created by the need matching system 200 by matching the unique item attributes in the unique attribute list exemplarily illustrated in FIG. 14C, with the need attributes in the second attribute list exemplarily illustrated in FIG. 14B. The attribute entry matching module 221 creates a attribute present entry with the amount present measure and the credibility measure as 0.37 and 1 respectively for MSWORD, from the predefined attribute table 224, that is, the attribute list database exemplarily illustrated in FIG. 14K. Similarly, the corresponding amount present measure and the corresponding credibility measure for EXCEL are 0.68 and 1 respectively as exemplarily illustrated in FIG. 14H.

FIG. 14I exemplarily illustrates the matched attribute list exemplarily illustrated in FIG. 14H, comprising attribute match scores generated by the score generation module 203 of the need matching system 200 exemplarily illustrated in FIG. 2, on matching the unique item attributes in the unique attribute list exemplarily illustrated in FIG. 14C, with the need attributes in the second attribute list exemplarily illustrated in FIG. 14B. The need match score generation module 228, exemplarily illustrated in FIG. 9, computes delta as difference in a attribute amount present measure and a attribute amount needed measure. As exemplarily illustrated in FIG. 14I, the delta for the matched attribute, MSWORD, is 0.370.20=0.17. The need match score generation module 228 determines an over/under adjustment using a lookup of (delta/attribute amount needed measure) against the amount measure deviation lookup table exemplarily illustrated in FIG. 14L. The value of (delta/attribute amount needed measure)=0.17/0.20=0.85. The corresponding over/under adjustment from the amount measure deviation lookup table is 0.20. The need match score generation module 228 computes the attribute match score as (importance measure*credibility measure*over/under adjustment)=0.80*1.00*0.20=0.16 as exemplarily illustrated in FIG. 14I. Similarly, for the other matched attributes, the need match score generation module 228 computes the attribute match scores as 0.21, 0.04, and 0.71 for the matched attributes EXCEL, CONFIDENCE, and DEPENDABILITY respectively.

FIG. 14J exemplarily illustrates a tabular representation for generation of a need match score defining the degree of match between the item profiles and the needs by the final match score generation module 231 exemplarily illustrated in FIG. 9. The final match score generation module 231 calculates a single numerical match score, that is, the need match score, as the Sum(attribute match score)/Sum(importance measure)=(0.16+0.21+0.04+0.71)/(0.80+0.30+0.40+0.90)=1.13/2.40=0.46960.47. The single numerical match score of 0.470 is different than 0.282 which is the simple average of the attribute match score without using importance as a weight.

FIG. 14K exemplarily illustrates a tabular representation of the default amount preset measure and the default credibility measure. For example, the item attribute of CONFIDENCE, if the isTrait representation is TRUE, the default amount measure is 0.5 and the corresponding credibility measure is 0.3. The item attribute of DEPENDABILITY, if the isTrait representation is TRUE, the default amount measure is 0.5 and the corresponding credibility measure is 0.25.

As exemplarily illustrated in the detailed description of FIGS. 14A-14L, for example, the need matching system 200 identifies EXCEL with 10 ratings and 2 of which are outliers. The item attribute with 8 ratings is considered to be of high credibility and the outliers are considered to be of low credibility. The amount present measure is 0.68 and is very close to the 8 ratings. The low credibility outliers have minimum effect. In another example, the need matching system 200 identifies MSWORD with 10 ratings and 2 of which are outliers. The item attributes with 8 ratings are considered to be of low credibility and the outliers are considered to be of high credibility. The amount present measure is 0.37 and is very close to the 2 high credibility outliers. In another example, the need matching system 200 identifies DEPENABILITY with 2 high credibility ratings. The amount present measure is midway between the two with higher credibility than either of the 2 ratings. In another example, the need matching system 200 identifies, CONFIDENCE with 2 low credibility ratings. The amount present measure is midway between the two and the same as for INTEGRITY, with higher credibility than either of the 2 ratings but much lower than that of INTEGRITY. The credibility of the individual ratings is based on the aggregated amount present measure. The outliers can be nearly ignored or very significant depending on their credibility. The credibility does not affect the amount present measure but affects the aggregated credibility which in turn affects the attribute match score.
