Retrieval type based patent retrieval system

Abstract

The invention provides a retrieval type based patent retrieval system. The retrieval type based patent retrieval system comprises an input module, a retrieval type generation module, a retrieval module, a database module and an output module, wherein the database module comprises a keyword bank unit and a retrieval database unit; the retrieval type generation module generates a retrieval type according to a retrieval tag input to the input module by the keyword bank unit and sends the retrieval type to the retrieval module; the retrieval module performs retrieval in the retrieval database unit according to the generated retrieval type; and the output module outputs a retrieval result. According to the retrieval type based patent retrieval system provided by the invention, the retrieval type is generated through the retrieval type generation module, so that the problem that a retrieval type made by a user cannot well meet user demands is solved, the operation is simple, the recall ratio and precision ratio of the retrieval result are increased, and the problems of repeated development and infringement are effectively avoided.

Description
