APPARATUS FOR PROVIDING DOCUMENT CLUSTERING USING RE-WEIGHTED TERM

摘要

A clustering apparatus and a method thereof are presented to minimize semantic difference between a cluster required by a user and a cluster provided by a system. According to a document clustering apparatus using a terminology weight recalculation, inputted document information is dissembled into each sentence information and invalid words are removed and primitive is extracted. A pre-processor(200) clusters documents on the basis of non-negative number matrix factorization, by generating a terminology-sentence matrix. A document clustering part(300) recalculates weight of the terminology and generates document clusters.
