CONCEPT DICTIONARY EXTENDING METHOD AND ITS DEVICE AND RECORDING MEDIUM WITH CONCEPT DICTIONARY EXTENDING PROGRAM RECORDED THEREON

摘要

PROBLEM TO BE SOLVED: To calculate the attribute vectors of specific nouns or new words which do not exist in a concept dictionary, and to add those attribute vectors to the concept dictionary.;SOLUTION: A relevancy calculating part 4 acquires the information of a user ID (or a terminal ID), retrieval words, and a retrieval time from a retrieval log in a retrieval log data base 3, and calculates relevancy among the retrieval words, and preserves relevant word data in a relevant data base 5. A new word vector calculating part 6 acquires relevant word data related with words read from a new word list 1 from the relevant word data base 5, and calculates the attribute vectors of new words by using word attribute vector information in a concept dictionary 2 and a temporarily preserved vector data base 7 based on the relevant word data, and outputs the attribute vectors of the new words to the temporarily preserved vector data base 7 or a new word dictionary 8.;COPYRIGHT: (C)2002,JPO
