RESOURCE SEARCH METHOD AND RESOURCE SEARCH SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a resource search method capable of effectively searching resources.;SOLUTION: Resource holding peers 5 can generate proper resource semantic vectors by generating resource semantic vectors on the basis of resource names and user evaluation values, so that effective resource search is possible. A query is transferred in a direction determined by a query semantic vector, and the query is transferred by flooding by index holding peers 4 to which the query is transferred, and index information is transmitted to a user peer 3 by an index holding peer 4 having index information of a resource corresponding to detailed information included in the query, out of peers to which the query is transferred by flooding. Thus a desired resource is searched with the peer holding index information of a resource approximating the desired resource, as the center in P2P search, so that effective resource search is possible.;COPYRIGHT: (C)2006,JPO&NCIPI
