Abstract

PROBLEM TO BE SOLVED: To provide a computer information processing technique for adopting knowledge and an ability to a system, which is provided by a talent employment consultant for placing a man of great enterprising with much experience, in a job offering and job hunting mediating system where job offering and job hunting information which is made into a database is processed by a computer and the combination of a job offering item and a job hunting item, which is well-adapted in mutual demands, is found. SOLUTION: When one job offering item is inputted as a retrieval condition, the job offering item is directly collated with the multiple job hunting items of a job hunting database and also indirectly collated with an example database and, then, minute information of some passing job hunting items is presented as a retrieval result. Simultaneously, the combination of a job offering skill phrase with a job hunting skill phrase, which is judged to be well adapted in the retrieval, is presented to a retrieval client or an example database manager and the input of an adaptability evaluation value concerning the combination is urged. The contents of the example database or the contents of an adaptability calculation algorithm is changed by improvement, based on the inputted adaptability evaluation value.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a job recruiting mediation system (a kind of expert system) which processes a job recruiting job in a database by a computer and finds a combination of job recruiting jobs and job recruiting jobs that match each other well. In particular, it relates to a mechanism for expressing the data of recruitment cases and job recruitment cases, a system for obtaining relevance between recruitment cases and job requisition cases by referring to cases, and a system for updating case information as needed.

[0002]

2. Description of the Related Art The following recruitment and job seeking information services by a computer information processing system are operated on the Internet. Job recruiting information collected from job applicants (job applicants) is stored in the database of the WWW server, and the recruiting company staff can operate the client computer to search and browse, and job recruitment collected from companies This is a system in which information is stored in a database of a WWW server so that a job applicant can operate a client computer to search and browse.

[0003] In this kind of employment information service system,
The user narrows down the number of cases matching the request to an appropriate number by a method such as keyword search or classification-based search, and examines the desired case by reading the contents.

[0004]

The job recruitment information service described above is a system in which a user searches a database of job recruitment information and job recruitment information. In order to improve the usability as viewed from the user, an easy-to-understand visual screen is provided. Improvements have been made in various aspects, such as developing a user interface based on the Internet, devising the description and format of information, and developing a high-speed and high-performance search engine. In any case, in the current system, either the job recruiter or the job seeker searches and browses the database, reads the contents of the searched information, and decides how and how it fits his wishes. You will decide for yourself. However, it is not easy for the parties themselves to determine exactly how and how each case fits their wishes, and in what areas and how they do not fit.

[0005] In considering matching between recruitment and job hunting, it is extremely important how to express a professional career. For example, the content of business in the high-tech advanced technology field related to computers and communications is being fragmented. Even with the concept of being integrated with computer application systems, the business contents differ greatly between financial systems and engineering systems, and the fields of application are diverse. For example, the concept of career, which is integrated with system development, differs greatly depending on whether you have gained experience as a project leader or focused on programming. Even in the concept of a career that is bundled with programming, the type of language to be used is important, and the ability to utilize a specific application program is often an issue.

[0006] In order to specify such a career concept as concretely and individually as possible, the description contents of recruitment and job search information will be diversified. This may also be a reason why the database cannot be used simply and effectively for those who cannot be used. In addition, even if carriers are described in specific and diverse ways, that does not directly lead to the judgment of "what kind of carrier can be transferred to another individual carrier", rather it is difficult to read information There is also the aspect of doing.

[0007] Therefore, specialists called human resource consultants are active. After receiving a job request from a company and a job request from an individual, they made a judgment that “this person in this career is suitable for this project of this company”, and specifically recruited companies and job seekers We are working to connect. This is a specialty profession that requires not only a very high level of business knowledge and abundant experience in recruiting, but also human judgment skills such as insight.

[0008] Since the contents of business in the high-tech advanced technology field are subdivided with the rapid progress, even human resources professionals such as recruitment consultants can properly understand the meaning of new technical terms related to the new business contents, and so on. It is not easy to accurately judge the suitability of job offers and job offers expressed in terms of technical terms. Experts, such as consultants, incorporate the changes of the subject into their knowledge by feeding their own knowledge of new successes and failures while performing day-to-day recruitment work.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a job recruiting mediation system that processes a database of job recruiting information with a computer and finds a combination of job recruiting and job recruiting items that match each other well. An object of the present invention is to provide computer information processing technology for incorporating the knowledge and capabilities of a rich and excellent recruitment consultant into a system. This allows
Discover the diverse possibilities of individuals, create optimal jobs and encounters with individuals, and realize a job recruiting and mediation system that can support the career design of many individuals.

[0010]

The recruiting and intermediary system according to the present invention is specified by the following items (10) to (20). (10) Information on occupational experience and background is expressed in skill phrases with a certain data format. The skill phrase is composed of a plurality of items having different attributes. For each attribute item, a number of keywords to be entered therein are predetermined, and a keyword that is arbitrarily selected from among those keyword groups is entered by a person accessing the system. (11) Individual appeal items for one job offer are expressed by a set of an arbitrary number of skill phrases. A set of skill phrases for a large number of job applications is recorded in the job application database. (12) A combination example of two skill phrases having a high degree of conformity is defined as a case skill phrase pair, and a number of case skill phrase pairs are created and recorded in the case database. Case weights related to the relevance of both phrases in each case skill phrase pair are set. (13) Items to be recruited for one job offer are expressed as a set of an arbitrary number of skill phrases. Each of the plurality of skill phrases included in one job offer is assigned a degree of importance. (14) One job offer A (i job offer skill phrase A
1, A2,..., Ai) are input as search conditions, and this job recruitment case A is directly collated with a large number of job recruitment cases in the job recruitment database, and is also transmitted via the case database. Match indirectly. (15) When the job offer case A is directly compared with the job offer case B (a set of j job offer skill phrases B1, B2,..., Bj), one job offer skill phrase An and j job offer skill phrases B1 , B2,..., Bj are matched one-to-one, and a phrase matching score representing the degree of matching between skill phrases is calculated for each combination of j sets of skill phrases. Is adopted as the direct matching phrase matching score Pn of the recruiting skill phrase An. where n = 1, 2,..., i
Direct matching phrase matching scores P1, P2,..., P for each of the skill phrases A1, A2,.
Find i. (16) In the indirect matching, each requisition skill phrase An (n = 1, 2,..., I) included in one requisition case A and a primary case phrase of many case skill phrase pairs are one-to-one. Matching is performed, and a primary case phrase that matches each requisition skill phrase An with a predetermined criterion or more is selected.
If a certain job recruiting skill phrase An matches the primary case phrase X of a certain case skill phrase pair XY, the secondary case phrase Y and each job recruiting skill phrase included in each job recruiting case are one-to-one. In addition, a job seeking skill phrase that matches the secondary case phrase Y and a predetermined criterion or more is selected. For the combination of the secondary case phrase Y and a certain job seeking case B, if the secondary case phrase Y best matches the certain job seeking skill phrase Bm, the relevance between the job offer skill phrase An and the primary case phrase X, Based on the matching degree between the secondary case phrase Y and the job seeking skill phrase Bm, and the case weight of the case skill phrase pair XY, a case intervening phrase matching score Qn between the job seeking skill phrase An and the job seeking skill phrase Bm is calculated. I do. (17) Recruiting skill phrase An and job recruiting skill phrase B
For the combination of m, the direct matching phrase matching score Pn
And the larger one of the case intervening phrase matching scores Qn is adopted as the genuine phrase matching score Rn. For the combination of job offer case A and job offer case B, i true phrase matching scores R1, R2, ..., Ri, the importance set for each job offer skill phrase An, and the number of phrases included in job offer case A i, and based on these
A job matching score representing the matching degree between the job matching job B and the job matching job B is calculated. (18) For one job A, several job offers that have scored higher than the specified criteria are passed, and these successful jobs are presented as search results to the search requesters who are accessing the system. I do. (19) A combination of a job recruiting skill phrase and a job recruiting skill phrase that has scored a genuine phrase matching score equal to or higher than a predetermined standard in a combination of the job recruiting case A and each successful job recruiting case, is expressed in a predetermined format, and the search requester or the case database is expressed. Present to the administrator as a phrase combination example. (20) Regarding individual combinations of recruiting skill phrases and job seeking skill phrases presented as phrase combining examples,
The relevance evaluation value given by the search requester or the case database administrator is input to the system. In response to the input of the suitability evaluation value, the contents of the case database or the contents of the suitability calculation algorithm are improved and changed.

In the present invention, preferably, as an improvement in the above item (20), a combination of a job recruiting skill phrase and a job recruiting skill phrase presented as the phrase combination example is used as a new case skill phrase pair. Register in the database. More preferably, the case database is logically divided into one shared case database and a plurality of individual case databases set for each search requester, and is added according to the input from the search requester. The new case skill phrase pair is registered in a specific individual case database assigned to the search requester. In this case, preferably, when the same case skill phrase pair is registered in the individual case database for a certain search requester and the shared case database, the search requester is set as the case weight related to the case skill phrase pair. The case relevance score is calculated using the case weight set in the individual case database. Preferably, the improvement in the above item (20) is a case skill phrase pair in a case database in a case database corresponding to a certain combination of a job recruiting skill phrase and a job seeking skill phrase presented as the phrase combination example. Changing the case weight is also included.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A job recruitment and mediation system according to the present invention is divided into two functions, a job recruitment case introduction system for presenting a job requisition to a job seeker and a job recruitment case introduction system for presenting a job requisition to a job seeker. it can. A job recruitment case introduction system is a system that, when a job recruitment case is entered in a predetermined format and expressed as data, the job recruitment case is compared with many job requisition cases stored in the database, Is a system that selects several job offers that satisfy the conditions, expresses the data in a predetermined format, and outputs the data. A job recruitment case introduction system is a system that matches a job requisition case with a large number of job requisition cases stored in a database when a job requisition case is entered in a specified format and entered into data. This is a system that selects several job seeking cases that satisfy the conditions, expresses the data in a predetermined format, and outputs the data.

The present invention is not related to a job recruitment case introduction system or a job recruitment case introduction system, but how well a data structure expressing a job requisition case and a job requisition case matches a certain job requisition case and a certain job requisition case. It is related to a technical mechanism for finding out whether or not a job offer case and a job offer case are collated via a case database, and a mechanism for improving the case database in a timely manner. Hereinafter, embodiments of the present invention will be described in detail according to the following items.

=== 1. Skill phrase data structure =
== Information on occupational experience and skills related to job offers and job offers is expressed in skill phrases with a certain data format. A skill phrase is composed of a plurality of items having different attributes. For each attribute item, a large number of keywords to be entered are predetermined, and a keyword arbitrarily selected from the keyword group is entered. FIG. 1 shows an example of the logical structure of a skill phrase. 1
The two job skill phrases are phrase IDs as keys
And job recruitment ID (or job requisition ID) indicating which job requisition matter (or job requisition matter) it is, four items of target business, business area, technology used, and interpersonal skills as attribute items, and importance of skill phrase Expressed by classification. The meaning of the four attribute items is as follows.

(1) Target task This is an item that describes the purpose of the task and the target of the task. The keywords to be entered in this item are shown in the table of FIG. In this example, many keywords are in three levels
It is sorted by a five-level tree-type logical structure. First
Under the hierarchical keyword "basic system", the second hierarchical keyword "open system""general-purposesystem"
"Device driver""GUI""Systemmigration"
Are linked, for example, below the “device driver”, the keywords of the third hierarchy “device driver general”, “ISDN port driver”, “WAN mini port driver”, “printer driver”, and “magnetic disk driver” are linked. doing. An appropriate one is selected from these keyword groups and entered in the target business item. Of course, each keyword is entered in code form.

(2) Business area This is an item that describes the contents of business, work or action, and also includes a level concept expressing the level of proficiency. Keywords to be entered in this item include, for example, "programming", "system development in general", "project leader", and "education".

(3) Technique used This is an item that describes the means of performing a task, and includes concepts such as methodology and knowledge. As keywords to be entered in this item, for example, “general-purpose machine”, “workstation”, “COBOL”, “UNIX”, “Visual Basic”
c "," TOEIC "," Intermediate English ", etc.

(4) Interpersonal Skills This is an item describing general so-called personal abilities such as interpersonal abilities and planning abilities. A keyword that should be entered in this field is, for example, "sales ability"
"Personal negotiation ability", "Planning ability", "Leadership", "Communication ability", etc.

=== 2. Recruiting Skill Phrases Set and Recruiting Database === As shown in FIG. 1B, the recruitment items for one recruiting case are expressed by a set of an arbitrary number of skill phrases. As mentioned above, each skill phrase has the phrase I
Since the job is managed with D and the job ID, a set of skill phrases included in one job case can be specified. Also,
Set the importance of each of the skill phrases included in one job offer. The importance is divided into three stages: sufficient conditions, necessary conditions, and additional elements. The sufficient condition is a condition that the job condition is considered to be satisfied if the skill condition expressed by the phrase is satisfied. The necessary condition is a condition required to satisfy the skill condition expressed by the phrase in order to meet the recruiting condition. The additional element is a condition determined to satisfy the skill condition expressed by the phrase in order to meet the recruiting condition, and is not necessarily required.

A recruiting database is constructed in this recruiting and recruiting intermediary system, and scheduled treatment data (described later) and a recruiting skill phrase set for a large number of recruiting cases are registered. As shown in FIG. 3, the recruitment database is logically divided into a scheduled treatment database in which scheduled treatment data is aggregated and a job recruitment skill database in which job skill phrase sets are aggregated.

=== 3. Job Skill Phrase Set and Job Search Database === Individual appeal items for one job search case are expressed by an arbitrary number of job search skill phrase sets. When registering this job seeking skill phrase set in the job seeking database, an individual phrase ID and a common job seeking ID are assigned to each job seeking skill phrase included in the set.

If it only functions as the recruitment case introduction system described above, there is no need for a job recruitment database.
In the case where the function as the job recruiting case introduction system described above is also added, a job recruiting database is required. This job hunting database is divided into a job hunting database that collects desired job treatment data to be described later and manages the job hunting IDs according to job hunting IDs, and a job hunting skill database that compiles job hunting skill phrases for each job hunting job and manages the job hunting IDs and phrase IDs It is constructed logically.

=== 4. Case skill phrase pair and case database === A combination case of two skill phrases having a high degree of conformity is taken as a case skill phrase pair, and many case skill phrase pairs are created and stored in the case database. For each example skill phrase pair, a case weight related to the fitness of both phrases is set. Suppose there is one case skill phrase pair B. The phrase pair B indicates a combination of the primary case phrase B1 and the secondary case phrase B2. In the indirect matching referring to the case described in detail below, the primary case phrase B1 in the case skill phrase pair B is matched with the recruiting skill phrase, and the secondary case phrase B2 is matched with the job seeking skill phrase (see FIG. 4). reference).

=== 5. Direct match phrase matching score ==
= A matching method for directly matching a skill phrase set of one job offer case with a skill phrase set of one job offer case is referred to as direct matching. In the direct matching, a job recruiting skill phrase and a job recruiting skill phrase are matched on a one-to-one basis, and a match / mismatch of keywords entered in the same attribute item is determined for both phrases. With the result of the determination as an input, a matching phrase matching score is obtained directly by the first calculation algorithm.

One job offer case is represented by i skill phrases A1, A2,..., Ai, and one job offer case is j skill phrases C1, C2,.
Let it be represented by It is assumed that the job offer and the job offer are to be directly compared. In the direct matching, first, one job recruiting skill phrase An (n = 1, 2,..., I) is compared with j individual skill phrases C1, C2,. With respect to the keywords, the match / mismatch / similarity of keywords entered in the same attribute item (four items of target business, business area, technology used, and interpersonal skill) is determined.

Next, a phrase matching score is calculated by the first calculation algorithm using the result of the determination as an input. In the first calculation algorithm, the higher the degree of matching and the degree of similarity of the keyword, the higher the phrase matching score. Preferably, an evaluation weight is set for each attribute item of the skill phrase, and in the first calculation algorithm, the result of determination of match / mismatch for each attribute item is scored according to the evaluation weight for each attribute item. Calculate the phrase match score.

=== 6. Indirect collation referring to examples === In determining the suitability between the skill phrase set of one job offer and the skill phrase set of one job offer,
A method of performing matching by interposing a large number of case skill phrase pairs stored in the case database is referred to as indirect matching.

(1) Primary Case Matching Score and Primary Hit Each recruiting skill phrase included in one recruiting case and a primary case phrase of a number of case skill phrase pairs are represented by one.
Matching is performed on a one-to-one basis, and a match / mismatch between keywords entered in the same attribute item for both phrases is determined. Using the result of the determination as an input, a primary case matching score is obtained by a third calculation algorithm. The third calculation algorithm is almost the same as the above-described first calculation algorithm, and the higher the degree of matching and similarity of the keyword, the higher the phrase matching score. The same applies to the reflection of the evaluation weight for each attribute item. For each recruiting skill phrase included in one recruiting case, a combination with the primary case phrase in which the primary case matching score is equal to or higher than the reference point is found. The combination of the recruiting skill phrase and the primary case phrase for which the primary case matching score is equal to or higher than the reference point is called a primary hit combination (see FIG. 5).

(2) Secondary Case Matching Score and Secondary Hit In the above-described matching process with the primary case phrase, the combination of the job offer skill phrase A and the primary skill phrase B1 of the case skill phrase pair B hits primary. And In that case, next, the secondary case phrase B2 of the case skill phrase pair B is matched one-to-one with each job search skill phrase included in one job search job, and the keyword of the keyword written in the same attribute item for both phrases is matched. Determine match / mismatch. Using the result of the determination as an input, a second case matching score is obtained by a fourth calculation algorithm. The fourth calculation algorithm is almost the same as the first and third calculation algorithms described above, and the higher the degree of matching and similarity of the keyword, the higher the phrase matching score. The same applies to the reflection of the evaluation weight for each attribute item. For each combination of the secondary case phrase B2 and each job seeking skill phrase, find a combination in which the secondary case matching score is equal to or higher than the reference point. The combination of the secondary case phrase and the job seeking skill phrase whose secondary case matching score is equal to or higher than the reference point is called a secondary hit combination (see FIG. 5).

(3) Indirect Hits and Case Intervening Phrase Match Score The case skill phrase pair B
If the combination of the secondary case phrase B2 and the job seeking skill phrase C makes a secondary hit, the job recruiting skill phrase A
And job seeking skill phrase C are case skill phrase pair B
Is determined to be appropriate via. This matching determination is called an indirect hit. If the job recruiting skill phrase A and the job recruiting skill phrase C are indirectly hit via the case skill phrase pair B, then a case-inclusive phrase matching score is obtained by the fifth calculation algorithm. The fifth calculation algorithm calculates the primary case recruitment skill phrase A and the primary case phrase B1 as the primary case matching score, the secondary hit secondary case phrase B2 and the job seeking phrase C as the secondary case matching score, Using the case weight of the phrase B as an input, a case intervening phrase matching score is calculated.
In the fifth calculation algorithm, the larger the primary case matching score, the secondary case matching score, and the case weight that are input, the larger the case intervening phrase matching score. When a job recruiting skill phrase indirectly hits a plurality of job recruiting skill phrases via a certain case skill phrase pair, only the indirect hit with the highest case intervening phrase matching score is adopted (FIG. 5).
See).

=== 7. Authentic phrase matching score and case matching score === A job recruiting skill phrase A and a job recruiting skill phrase C
The match score for the direct match phrase for the combination of (ac
Assume that 1). It is assumed that the job recruiting skill phrase A and the job recruiting skill phrase C are indirectly hit via one or more case phrase pairs, and one or more case intervening phrase matching scores (ac2) (ac3). In this case, the maximum score among these phrase matching scores (ac1) (ac2) (ac3)... Is adopted as a genuine phrase matching score of the combination of the recruiting skill phrase A and the job seeking skill phrase C (see FIG. 6). .

In order to determine the relevance between one job offer and one job offer, one-to-one recruitment skill phrases and job offer skill phrases generated from the skill phrase set of the job offer and the skill phrase set of the job offer are required. Perform the direct and indirect matching described above for the combination. Thus, it is assumed that one or more true phrase matching scores have been adopted for a combination of one job offer case and one job offer case. Each genuine phrase matching score obtained here, the importance set for each recruiting skill phrase,
The number of phrases in the skill phrase set of one requisition case is input, and a case relevance score is obtained by quantifying the relevance between the requisition case and the job requisition case using the sixth calculation algorithm. In the sixth calculation algorithm, the higher the true phrase matching score, the larger the case matching score. In addition, the higher the importance set for each skill phrase, the greater the calculational evaluation of the corresponding true phrase matching score. Also, the larger the number of phrases, the smaller the calculated evaluation of one true phrase matching score. It is also possible to employ an algorithm that groups skill phrases according to their importance, and calculates a case matching score based on the number of phrases for each importance group and a genuine phrase matching score. Through the above process, a case relevance score is calculated by quantifying how and which one job recruitment case matches one job recruitment case.

=== 8. Job recruitment case introduction system === For example, a job seeker operates his / her own computer and accesses a server computer of a job recruitment case introduction system (a job recruitment job intermediation system of the present invention) via a communication medium such as the Internet to be guided. According to the procedure, the data (job skill phrase set) expressing one's own job application is delivered to the server. In response to this, the server collates the input job recruitment case with a large number of job requisition cases stored in the job recruitment database as follows, and outputs the collation result to the job seeker computer as follows. The basics of the processing process are as follows. It is assumed that 10,000 recruiting cases are registered in the recruiting database, for example. It is also assumed that 1,000 case skill phrase pairs are registered in the case database. For all combinations of one job offer presented by a job seeker and 10,000 job offers registered in the recruitment database, the above-mentioned direct collation and indirect through 1,000 case skill phrase pairs The collation is executed, and 10,000 case matching scores are calculated. From the 10,000 job matching scores, select job openings that score above the reference score. A job offer selected in this process is referred to as a successful job offer. The detailed information of the successful recruiting case is edited into a predetermined HTML document format that is easy for the job seeker to understand, and transmitted to the job seeker computer. In this way, the detailed information of the recruiting case selected by the matching search is displayed on the screen of the job recruiter computer that has expressed the job recruiting case with the job recruiting skill phrase set and entered the system.

=== 9. Job recruiting case introduction system === For example, a job recruiting company representative operates a required computer, accesses a server computer via communication media such as the Internet, and expresses a job recruiting skill phrase set according to the guided procedure. To the server. In response to this, the server sends the entered 1
The job requisitions are collated with a large number of job requisitions in the requisition database as follows, and the collation result is output to the recruiting company computer as follows. 8 in the job search database
It is assumed that 1,000 job offers have been registered. It is also assumed that 1,000 case skill phrase pairs are registered in the case database. For all combinations of one job offer presented by the recruiting company and 8,000 job offers registered in the job recruitment database, the direct collation described above and the indirect intermediation of 1,000 example skill phrase pairs The matching is executed to calculate 8,000 case matching points.

From among the 8,000 job matching scores, a job seeking job with a score above the reference score is selected. The job offer selected in this process is referred to as a successful job offer. The detailed information of the successful job application is edited into a predetermined HTML document format that is easy for the recruiter to understand, and sent to the recruiting company computer. In this way, the detailed information of the job offer selected by the matching search is displayed on the screen of the recruiting company computer which has entered the system by expressing the job offer with the job offer skill phrase set.

=== 10. Individual Case Database === As shown in FIG. 3, the case database is logically divided into one shared case database and a plurality of individual case databases set for each search requester. The search requester here means each recruiting company that has registered a job offer. When a person in charge of a recruiting company uses a job recruiting case introduction system as a search requester, a shared case database and an individual case database dedicated to the company are used for indirect collation. At this time, if the same case phrase pair exists in both the shared case database and the individual case database, the individual case database has priority. That is, the case intervening phrase matching score is calculated using the case weights assigned to the case phrase pairs in the individual case database.

=== 11. Example improvement function attached to the job recruitment case introduction system === As explained in the previous section, the person in charge of the recruiting company accesses the server computer by operating the required computer, and sets the recruiting skill phrase set as search conditions to the server. Deliver. In response to this, the server sends the entered 1
The job requisitions are compared with a large number of job requisitions in the recruitment database as follows, and some successful job requisitions are extracted, and the detailed information on the job requisitions is transmitted to the recruiting company computer. The following processing is performed accompanying this process.

The server expresses, in a predetermined format, a combination of a job recruiting skill phrase and a job recruiting skill phrase that have scored a genuine phrase matching score that is equal to or greater than a specified value in a combination of one job recruiting item and each passing job recruiting item that has become a search condition. Then, it is presented to the recruiter who requested the search as a phrase combination example (displayed on the recruiting company computer).

On the screen expressed in HTML, a recruiting person operating a recruiting company computer enters a suitability evaluation value for each combination of a recruiting skill phrase and a job recruiting skill phrase presented as a phrase combination example. There is. The recruiter reads the recruiting skill phrase and the job recruiting skill phrase as phrase combining examples displayed on the screen, and based on his / her expertise, determines whether the combination really fits.
Consider how valid the determination of conformance is, and whether the determination of conformity is not an error. The result of the consideration is written in the suitability evaluation value entry column of each phrase combination example. The suitability evaluation value is expressed, for example, in three stages of ○ ××. A combination of “good” is marked with ◎, a combination of “matched” is marked with “○”, and a combination of “not fit” is marked with x.

The server obtains the suitability evaluation value attached to each phrase matching case on the screen of the recruiting company computer, and improves the contents of the company-specific individual case database based on the matching evaluation value. . The process of changing in an improving manner is performed, for example, as follows. If there is no phrase combination case marked with ◎ or に in the individual case database, the combination case is registered in the individual case database as a new case phrase pair. At this time, the case weight is set so that the pair marked with ◎ is larger than the pair marked with ○. If the combined case with ◎ already exists in the individual case database, the case weight of the pair is appropriately increased. When a combined case marked with “x” exists in the individual case database, the case weight of the pair is appropriately reduced or the pair is deleted from the individual case database.

As described above, the contents of the individual case database dedicated to each recruiting company are changed and improved in accordance with the judgment of the person in charge. As a result, the personnel experience of the company is reflected in the accuracy of the indirect collation, and the ability of the matching system is improved in a learning manner.

=== 12. Consultant support tool ==
= This recruitment and recruitment mediation system is operated by, for example, a recruitment consulting company, and is released to the outside as a recruitment case introduction system in which job seekers search and browse the recruitment database, and as a job recruitment case introduction system in which recruiting companies search and browse the recruitment database. In addition to this, the consultant will use it as a support tool for the recruitment work as an internal system of the recruitment consulting company.

The basic functions as a consultant support tool are almost the same as the functions of the recruitment case introduction system and the job recruitment case introduction system described above. By operating the computer for the consultant, the case can be appropriately extracted from the job recruitment database or the job recruitment database, and based on this, the consultant sets search conditions and searches the job recruitment database or the job recruitment database. Through such work, a specific job offer and a specific job offer are selected, and the relevant job seeker is recruited to a job recruiter and interviewed.

The above-described case improvement function is also realized in the operation mode of the consultant support tool. The job search database is searched using the job offer set by the consultant as a search condition, and some successful job offer are presented to the consultant. At the same time, several phrase combination cases are presented to the consultant, and each of the combination cases can be given a suitability score by the consultant. The server improves the content of the case database or the content of the fitness calculation algorithm based on the fitness evaluation value given by the consultant. In this case, the shared case database is also an object to be improved.

[0046]

According to the present invention, an individual appeal matter for one job seeker is expressed by a set of an arbitrary number of skill phrases, and a set of skill phrases of a large number of job seekers are registered in a job seeker database. Also, a combination example of two skill phrases having a high degree of matching is defined as a case skill phrase pair, and a number of case skill phrase pairs are created and registered in the case database. Also, one requisition case as a search condition is represented by an arbitrary number of recruitment skill phrase sets. When one job offer is input as a search condition, the job offer is directly collated with a large number of job offers in the job recruitment database, and indirectly collated via the case database. The detailed information of the successful job application is presented as a search result. At the same time, a combination of a job recruiting skill phrase and a job recruiting skill phrase that are determined to be well matched in the search is presented to a search requester or a case database administrator, and the user is prompted to input a fitness evaluation value for the combination. The contents of the case database or the contents of the suitability calculation algorithm are improved based on the inputted suitability evaluation value.

With this mechanism, a job recruiting mediation system that processes a database of job recruiting information by computer and finds a combination of job recruiting and job recruiting cases that match each other's needs well is rich in experience and enterprising. Automatically and learningly incorporate the knowledge and abilities of a good recruitment consultant into the system. As a result, a person in a position such as a recruiter's search engineer or recruitment consultant can use this system to search the contents of the case database based on successful or unsuccessful job recruitment matching or the chronological change of the target business. Can be easily improved, the system can be prevented from becoming obsolete, and the matching search ability can be constantly improved.

(10) Information on occupational experience and background is expressed in skill phrases with a certain data format. The skill phrase is composed of a plurality of items having different attributes. For each attribute item, a number of keywords to be entered therein are predetermined, and a keyword that is arbitrarily selected from among those keyword groups is entered by a person accessing the system. (11) Individual appeal items for one job offer are expressed by a set of an arbitrary number of skill phrases. A set of skill phrases for a large number of job applications is recorded in the job application database. (12) A combination example of two skill phrases having a high degree of conformity is defined as a case skill phrase pair, and a number of case skill phrase pairs are created and recorded in the case database. Case weights related to the relevance of both phrases in each case skill phrase pair are set. (13) Items to be recruited for one job offer are expressed as a set of an arbitrary number of skill phrases. Each of the plurality of skill phrases included in one job offer is assigned a degree of importance. (14) One job offer A (i job offer skill phrase A
1, A2,..., Ai) are input as search conditions, and this job recruitment case A is directly collated with a large number of job recruitment cases in the job recruitment database, and is also transmitted via the case database. Match indirectly. (15) When the job offer case A is directly compared with the job offer case B (a set of j job offer skill phrases B1, B2,..., Bj), one job offer skill phrase An and j job offer skill phrases B1 , B2,..., Bj are matched one-to-one, and a phrase matching score representing the degree of matching between skill phrases is calculated for each combination of j sets of skill phrases. Is adopted as the direct matching phrase matching score Pn of the recruiting skill phrase An. where n = 1, 2,..., i
Direct matching phrase matching scores P1, P2,..., P for each of the skill phrases A1, A2,.
Find i. (16) In the indirect matching, each requisition skill phrase An (n = 1, 2,..., I) included in one requisition case A and a primary case phrase of many case skill phrase pairs are one-to-one. Matching is performed, and a primary case phrase that matches each requisition skill phrase An with a predetermined criterion or more is selected.
If a certain job recruiting skill phrase An matches the primary case phrase X of a certain case skill phrase pair XY, the secondary case phrase Y and each job recruiting skill phrase included in each job recruiting case are one-to-one. In addition, a job seeking skill phrase that matches the secondary case phrase Y and a predetermined criterion or more is selected. For the combination of the secondary case phrase Y and a certain job seeking case B, if the secondary case phrase Y best matches the certain job seeking skill phrase Bm, the relevance between the job offer skill phrase An and the primary case phrase X, Based on the matching degree between the secondary case phrase Y and the job seeking skill phrase Bm, and the case weight of the case skill phrase pair XY, a case intervening phrase matching score Qn between the job seeking skill phrase An and the job seeking skill phrase Bm is calculated.
