Information classification device, information classification method, and computer readable recording medium

An information classification method for classifying contents targeted for classification into a category, comprising the steps of:

• (a) performing, using at least one processor, correct/incorrect determination on the contents targeted for classification, using a plurality of first rules, each of which includes a rule condition specifying a condition of a rule and a corresponding score specifying a value in a case where the rule condition matches the contents targeted for classification, wherein the performing the correct/incorrect determination includes applying each of the plurality of first rules to the contents targeted for classification, calculating a total score of each of the contents targeted for classification based on the corresponding scores of the rule conditions matching each of the contents targeted for classification, determining a content among the contents targeted for classification to be correct, in response to the calculated total score of the content being greater than a predetermined threshold, and determining a content among the contents targeted for classification to be incorrect, in response to the calculated total score of the content being less than the predetermined threshold;
• and
• (b) applying, using the at least one processor, each of a plurality of second rules having mutually different conditions and including a judge ID specifying a corresponding judge, to the content determined to be correct in the step (a), and determining, using the at least one processor, whether the condition is met, and
• comparing, using at least one processor, a number of second rules that agree with the determination result of the first determination unit to a number of second rules that do not agree with the determination result of the first determination unit, wherein
• when there are more rules that agree with the determination result of the first determination unit than rules that do not agree with the determination result of the first determination unit, correct/incorrect determination is performed by the second determination unit in the same way as the first determination unit, and
• when there are more rules that do not agree with the determination result of the first determination unit than rules that agree with the determination result of the first determination unit, correct/incorrect determination is not performed in the same way as the first determination unit,
• wherein each of the plurality of first rules is created using a result of correct/incorrect determination executed in advance on each of a plurality of contents that are different from the contents targeted for classification by two or more people and a feature amount of each of the plurality of different contents, and
• each of the plurality of second rules is created to correspond to a different one of the two or more people, using the result of correct/incorrect determination executed in advance by the two or more people and the feature amount.

A non-transitory computer readable recording medium having recorded thereon a program for causing a computer to execute classification of contents targeted for classification into a category, the program including a command for causing the computer to execute the steps of:

• (a) performing correct/incorrect determination on the contents targeted for classification, using a plurality of first rules, each of which includes a rule condition specifying a condition of a rule and a corresponding score specifying a value in a case where the rule condition matches the contents targeted for classification, wherein the performing the correct/incorrect determination includes applying each of the plurality of first rules to the contents targeted for classification, calculating a total score of each of the contents targeted for classification based on the corresponding scores of the rule conditions matching each of the contents targeted for classification, determining a content among the contents targeted for classification to be correct, in response to the calculated total score of the content being greater than a predetermined threshold, and determining a content among the contents targeted for classification to be incorrect, in response to the calculated total score of the content being less than the predetermined threshold;
• and
• (b) applying each of a plurality of second rules having mutually different conditions and including a judge ID specifying a corresponding judge, to the content determined to be correct in the step (a) and determining whether the condition is met, and
• comparing a number of second rules that agree with the determination result of the first determination unit to a number of second rules that do not agree with the determination result of the first determination unit, wherein
• when there are more rules that agree with the determination result of the first determination unit than rules that do not agree with the determination result of the first determination unit, correct/incorrect determination is performed by the second determination unit in the same way as the first determination unit, and
• when there are more rules that do not agree with the determination result of the first determination unit than rules that agree with the determination result of the first determination unit, correct/incorrect determination is not performed in the same way as the first determination unit,
• wherein each of the plurality of first rules is created using a result of correct/incorrect determination executed in advance on each of a plurality of contents that are different from the contents targeted for classification by two or more people and a feature amount of each of the plurality of different contents, and
• each of the plurality of second rules is created to correspond to a different one of the two or more people, using the result of correct/incorrect determination executed in advance by the two or more people and the feature amount.
