WORD SIGNIFICANCE CALCULATING METHOD, DEVICE, PROGRAM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To calculate significance of a retrieving word. SOLUTION: First of all, a category information input part 101 inputs a category being front information for an automatic classifying system to automatically classify the category and a sample document allocated to the category. Next, a retrieval recording extracting part 102 extracts information on 'a retrieving word' and 'a selected category' from retrieval input recording recorded by retrieval service. A retrieval recording totalizing part 103 totalizes an input frequency of the retrieving word with respective categories. A category information learning part 104 extracts a word existing in a document from data acquired by the category information input part 101, and totalizes the word with respective categories, and calculates significance of the word to the respective categories by also using data acquired by the retrieval recording totalizing part 103. A result output part 105 outputs a result determined by the category information learning part 104 to a display. COPYRIGHT: (C)2003,JPO
