摘要

PROBLEM TO BE SOLVED: To perform OR retrieval including a plurality of designated concepts or NOT retrieval excluding the designated concept, and to precisely extract a target document by designating a concept to be added and a concept to be excluded in detail.;SOLUTION: A concept retrieval method includes: obtaining the concept vectors (retrieval vectors) of retrieval words or retrieval documents; obtaining the concept vectors (retrieval condition vectors) of words or documents included as additional retrieval conditions; obtaining retrieved vectors from the concept vector storage means in which the concept vectors (retrieved vectors) of a plurality of words or a plurality of documents to be retrieved are stored; and calculating distances between the retrieved vectors and the retrieval vectors and the retrieval condition vectors.;COPYRIGHT: (C)2010,JPO&INPIT
