PROBLEM TO BE SOLVED: To easily and efficiently classify a document retrieved by concept retrieval. SOLUTION: This cluster analyzing device is provided with terminal equipment 1 for a user which inputs a retrieval sentence, or outputs a retrieval result, a retrieval device 2 which performs the retrieval processing of a technical document such as a patent document based on the retrieval sentence and terminal equipment 3 for management which registers the technical document such as the patent document in the retrieval device 2. Each word obtained by operating morphemic analysis to the technical document retrieved by the concept retrieval is weighted, and each technical document is vectorized, and the technical documents whose vector directions are close are gathered into one cluster. Thus, it is possible to efficiently classify a large amount of technical documents into several clusters. COPYRIGHT: (C)2005,JPO&NCIPI
