Industry keyword-based patent retrieval system

Abstract

The invention provides an industry keyword-based patent retrieval system. The system comprises a keyword analysis module, a patent database module and a matching search module, wherein patent literatures in the patent database module are divided into a plurality of industry categories; the keyword analysis module performs splitting on a technical document, extracts technical keywords, and returns the technical keywords to the matching search module; the industry category with the highest keyword matching degree is taken as the industry involved by the technical document; and the sorting is performed from high to low according to the keyword matching degrees, and the retrieved patent literatures are sorted and output. According to the industry keyword-based patent retrieval system provided by the invention, the technical field which the technical document belongs to is judged according to an industry keyword involved by the to-be-retrieved technical document first and then patent files in the technical field which the technical document belongs to are retrieved, so that the accuracy of retrieval results is higher.

Description

technical field [0001] The invention belongs to the field of patent information technology analysis, in particular to a patent retrieval system based on industry keywords. Background technique [0002] The patent retrieval systems provided by the prior art are all retrieval systems that directly input keywords and then conduct technology searches directly based on keywords. However, it often happens that the technologies retrieved do not belong to the same industry field, resulting in the retrieval of patent documents. The value is relatively low and has no practical significance. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a patent retrieval system based on industry keywords, which includes a keyword analysis module, a patent database module, and a matching search module; [0004] The patent documents in the patent database module are divided into several industry classifications, and the patent docume...
