INTRINSIC EXPRESSION EXTRACTION RULE GENERATION SYSTEM AND METHOD, RECORDING MEDIUM RECORDED WITH PROCESSING PROGRAM THEREFOR, AND INTRINSIC EXPRESSION EXTRACTION DEVICE

摘要

PROBLEM TO BE SOLVED: To solve the problem that a highly accurate intrinsic expression extraction rule can not be easily generated in a short time and a desired intrinsic expression can not be accurately extracted from huge documents by a conventional technique. SOLUTION: Respective words are extracted from a prepared document 1 for training by a morpheme analysis/part-of-speech character kind imparting part 3 first and then, the rules for intrinsic expression extraction are generated based on the respective words and a correct answer list 2 prepared corresponding to the document 1 for training by a rule generation part 4. Then, by a training rule application part 6, the rules are respectively independently applied to the document 1 for training and intrinsic expression extracted results for the respective rules are obtained. By a rule evaluation part 8, the intrinsic expressions obtained by the applied results and the correct answer list are compared and the appropriateness of the respective rules is compared. On the basis of the result, by a rule elimination part 9 and a rule refining part 10, the rules are appropriately eliminated and corrected.
