RETRIEVAL DATA BASE CONSTRUCTION METHOD, SYSTEM THEREFOR AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To extract the important words, etc., from the files for construction of a retrieval data base by retrieving the punctuation symbols out of the character strings of the retrieved files, extracting the words which are held between the punctuation symbols and accumulating the extracted words for every retrieved file in the form of a retrieval data base. ;SOLUTION: This system includes a storage A which stores the information and a data processor B which operates under the control of a program. The storage A includes an input file storage part 1 which stores plural files to be retrieved, a key storage part 3 which stores the keys used for preparing a data base and a retrieval data base storage part 4 which stores the produced data. Meanwhile, the processor B includes a file type discrimination part 21 which discriminates the types of files which are read out of the part 1 and a word retrieval part 22 which retrieves and extracts the words based on the file types and the retrieval keys stored in the part 3. Thus, the processor B forms a retrieval data base production part 2.;COPYRIGHT: (C)1999,JPO
