DEVICE AND METHOD FOR GENERATING THESAURUS AND STORAGE MEDIUM RECORDING THESAURUS GENERATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To reduce the burden of work for registering a word on a thesaurus and registering data indicating a semantic relationship. SOLUTION: A sentence inputted while using an input device is analyzed by morpheme analysis and a word (noun) is extracted. When the extracted word is not registered on the thesaurus yet, that word is newly registered on the thesaurus. The inclusive relation of a character code is decided between the word newly registered on the thesaurus and the word already registered on the thesaurus. Corresponding to the decision result, the relation data indicating the relationship of a high-order (BT) or low-order (NT) concept between the newly registered word and the registered word are registered on the thesaurus.
