Information extraction rule creation support system, information extraction rule creation support method, and information extraction rule creation support program

摘要

A support function capable of efficiently creating an extraction rule for extracting desired information without inputting a large amount of teacher data in advance is provided. In the information extraction rule creation support system, the extraction rule input means 10 receives input of a plurality of extraction rules. The storage device 2 stores the extraction target document in advance. The extraction rule application unit 11 obtains an extraction result from the extraction target document based on the extraction rule. The rule relation generation unit 12 compares the obtained extraction results between the extraction rules, and the rule that associates the data of the rule relation network that is in the overlapping relation or the inclusion relation from the extraction rules that satisfy the predetermined condition with the extraction result. Generate relationship information. The rule relation output unit 13 outputs the rule relation information generated by the rule relation generation unit.
