摘要

PROBLEM TO BE SOLVED: To realize a key concept extraction rule preparing device capable of preparing an extraction rule for extracting a key concept as the key concept from a document. SOLUTION: The key concept extraction rule preparing device performs morphological analysis of document data and displays the result of the morphological analysis. A user segments a part equivalent to the key concept from in the displayed result and registers it with the key concept. The key concept extraction rule preparing device generates example data including the morpheme data of the document data from the document data, acquires a key concept extraction rule for extracting the candidate of the key concept based on the generated example data and stores the acquired extraction rule in a memory.
