SUMMARY REGISTERING APPARATUS, SUMMARY REGISTRATION METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To efficiently generate a summary on which the retrieval intention of a user is reflected.;SOLUTION: A registration part 10 retrieves document data related to a designated index word from a document data group being a retrieval object, and returns the document data as the retrieval result. In a summary group storage part 20 which stores the summary data of the document data, the summary data of the document data being a new retrieval object is registered. Furthermore, the registration part 10 divides the document data being the new retrieval object into frame units, and extracts each index word from each phrase included in a frame group obtained by dividing the document data. Then, the registration part 10 preferentially selects the frame including the index word which does not overlap another phrase from the phrase group, and registers the phrase in a summary group storage part 20 as the summary data of the new document data.;COPYRIGHT: (C)2005,JPO&NCIPI
