DOCUMENT MULTI-CLASSIFICATION DEVICE AND DOCUMENT MULTI-CLASSIFICATION METHOD FOR CLASSIFYING ONE DOCUMENT INTO PLURALITY OF CATEGORIES BY USING LEXICO-SEMANTIC PATTERN OBTAINED BY RECONFIGURING SEMANTIC CATEGORY OF WORDS CONSTITUTING SENTENCE

摘要

The present invention relates to a document multi-classification device and method for classifying one document into a plurality of categories by using a lexico-semantic pattern (LSP) obtained by reconfiguring a semantic category of words constituting a sentence. The present invention comprises: a pre-processing unit for defining an LSP, which includes a morpheme, a syllable, and a word phrase, and storing the same in a database, and defining a concept, which is a group of a plurality of hierarchically structured LSPs, and storing the same in the database; an analysis unit performing morpheme analysis on a sentence included in a document to be analyzed, and matching the same to the LSP so as to calculate a syntax analysis resu and a classification unit matching the syntax analysis result according to a document classification rule so as to extract at least one document classification of the document to be analyzed.
