摘要

PPROBLEM TO BE SOLVED: To provide a system and a method based on the identification of a cluster of elements (e.g. documents) indicating a degree of high mutual similarity with a background for information retrieval and data mining of a large-scale text database. PSOLUTION: The computer system comprises a neighborhood patch generation part 34 for generating data structure for the information retrieval of documents stored in the database and generating a node group having prescribed similarities in a hierarchy structure. The neighborhood patch generation part 34 comprises a hierarchy generation part 36 for generating hierarchy structure upon document-keyword vectors and a patch definition part 26. The computer system comprises a cluster estimation part 28 for generating cluster data of the document-keyword vectors by using the similarities of patches. PCOPYRIGHT: (C)2004,JPO&NCIPI
