LITERATURE RETRIEVAL DEVICE, LITERATURE RETRIEVAL SUPPORT METHOD AND LITERATURE RETRIEVAL METHOD

摘要

PURPOSE: To reduce the retrieval burden of a user and to prevent a retrieval omission and errorneous retrieval by converting an input keyword into a keyword used in a data base based on past retrieval and executing retrieval. ;CONSTITUTION: A keyword conversion part 2 refers to a keyword conversion accumulation part 9 with the inputted input keyword and retrieves a retrieval keyword. When the retrieval keyword corresponding to the input keyword can be retrieved, the data base 6 is retrieved with the obtained retrieval keyword. When the literature of the desired data base 6 can be retrieved, a processing is terminated. When the retrieval keyword corresponding to the input keyword cannot be obtained, the keyword for data base retrieval is generated by a keyword connection part 3, a retrieval expression generation part 4, a literature selection part 7 and a keyword conversion data generation part 8, and the data base 6 is retrieved with the retrieval keyword generated by a data base retrieval part 5. When desired literature is obtained, the input/output keywords are accumulated in the accumulation part 9.;COPYRIGHT: (C)1995,JPO
