DEVICE AND METHOD FOR CLASSIFYING QUESTION DOCUMENTS AND RECORD MEDIUM WHERE PROGRAM WHEREIN SAME METHOD IS DESCRIBED IS RECORDED

摘要

PROBLEM TO BE SOLVED: To retrieve a category matching the question contents of a question document with high precision by using a feature quantity extracted from constituent elements of the question document corresponding to an answer document included in the category when the feature quantity of the extracted category is calculated. ;SOLUTION: Individual documents are extracted from an answer document set and documents are put together form a question document set (S1, S2). Those individual documents are classified (S3) after they are decomposed into words and morpheme analysis is carried out to calculate feature vectors. After the classified answer documents are held (S4), feature vectors are calculated as to the question documents and classification category feature quantities are calculated (S6) while made to correspond to the answer documents. Then a new question document is extracted (S7), a feature vector is calculated as to the new document to calculate the adaptivity to the held classification category (S8), and a specific number of matching categories from the top are gathered (S9).;COPYRIGHT: (C)2000,JPO
