Information matching apparatus, method of matching information, and computer readable storage medium having stored information matching program

Abstract

The information matching apparatus includes: a training data setting unit that sets supervised data in a machine learning device of supervised learning that learns judgment criteria used for a judgment of identicalness, similarity, and relevance between a plurality of records by matching the records configured by sets of values corresponding to items; a check point setting unit that sets a check point configured by one set of two records used for evaluating the set supervised data; and a learning result evaluation unit, for the set check point, acquires a change between a judgment result using judgment criteria derived as a result of learning based on set first supervised data and a judgment result using judgment criteria derived as a result of learning based on set second supervised data set and evaluates the supervised data based on the acquired change.

 a processor; and   a memory, wherein the processor executes:   setting supervised data in a machine learning device of supervised learning that learns judgment criteria used for a judgment of identicalness, similarity, and relevance between a plurality of records by matching the records configured by sets of values corresponding to items;   setting a check point configured by one set of two records used for evaluating the supervised data set at the setting supervised data; and   evaluating, for the check point set at the setting a check point, by acquiring a change between a judgment result using judgment criteria derived as a result of learning based on first supervised data set at the setting supervised data and a judgment result using judgment criteria derived as a result of learning based on second supervised data set at the setting supervised data and by evaluating the supervised data based on the acquired change.   
     
     
         2 . The information matching apparatus according to  claim 1 , wherein the evaluating, includes a reflecting that analyzes an evaluation result that is evaluated and reflects the evaluation result on the supervised data. 
     
     
         3 . The information matching apparatus according to  claim 1 , wherein the evaluating, for a plurality of the check points of which expected values are known in advance, acquires a change between a ratio of the check points having the judgment result using the judgment criteria based on the first supervised data as the expected value and a ratio of the check points having the judgment result using the judgment criteria based on the second supervised data as the expected value. 
     
     
         4 . The information matching apparatus according to  claim 1 , wherein the evaluating, for a plurality of the check points, acquires a change between the number of the check points for each judgment result using the judgment criteria of the first supervised data and the number of the check points for each judgment result using the judgment criteria of the second supervised data. 
     
     
         5 . The information matching apparatus according to  claim 1 , wherein the evaluating, for a plurality of the check points of which expected values are known in advance, acquires a change between whether the judgment result using the judgment criteria of the first supervised data matches with the expected value and whether the judgment result using the judgment criteria of the second supervised data matches with the expected value. 
     
     
         6 . The information matching apparatus according to  claim 1 , wherein the evaluating, for each check point, acquires a change between the judgment result using the judgment criteria of the first supervised data and the judgment result using the judgment criteria of the second supervised data. 
     
     
         7 . The information matching apparatus according to  claim 1 , wherein the evaluating, for each check point, acquires a change between a degree for judging identicalness as the judgment result using the judgment criteria of the first supervised data and a degree for judging identicalness as the judgment result using the judgment criteria of the second supervised data. 
     
     
         8 . The information matching apparatus according to  claim 1 , wherein the evaluating, for the check point, acquires a change between a maximum of a degree as the judgment result using the judgment criteria of the first supervised data and a maximum of a degree as the judgment result using the judgment criteria of the second supervised data. 
     
     
         9 . The information matching apparatus according to  claim 1 , wherein the evaluating, acquires a change between the judgment criteria used for the judgment of the first supervised data and the judgment criteria used for the judgment of the second supervised data set by the training data setting unit. 
     
     
         10 . The information matching apparatus according to  claim 1 , wherein the setting check point, selects the check point out of the supervised data and sets the selected check point. 
     
     
         11 . A non-transitory computer readable storage medium having stored therein an information matching program causing an information matching apparatus to execute a process comprising:
 setting supervised data in a machine learning device of supervised learning that learns judgment criteria used for a judgment of identicalness, similarity, and relevance between a plurality of records by matching the records configured by sets of values corresponding to items;   setting a check point configured by one set of two records used for evaluating the set supervised data; and   acquiring a change between a judgment result using judgment criteria derived as a result of learning based on set first supervised data and a judgment result using judgment criteria derived as a result of learning based on set second supervised data for the set check point and evaluating the supervised data based on the acquired change.   
     
     
         12 . A method of matching information performed by an information matching apparatus, the method comprising:
 setting supervised data in a machine learning device of supervised learning that learns judgment criteria used for a judgment of identicalness, similarity, and relevance between a plurality of records by matching the records configured by sets of values corresponding to items;   setting a check point configured by one set of two records used for evaluating the set supervised data; and   acquiring a change between a judgment result using judgment criteria derived as a result of learning based on set first supervised data and a judgment result using judgment criteria derived as a result of learning based on set second supervised data for the set check point and evaluating the supervised data based on the acquired change.
