CN101025753A - Patent search method - Google Patents

Abstract

The invention is a patent is a patent searching method, firstly pre-establishing an extended database stored with extended keywords matching with various searching keywords, then determining the extended keywords matching with the searcher-input keywords according to the extended database, successively searching the specified patent database and obtaining the corresponding searching results according to the searcher-input keywords and the extended keywords, and finally displaying the searching results, thus able to reduce searching leakage rate and raise the searchers' working efficiency by automatic extension to explanation of keywords.

Description

Patent retrieval method

Technical field

The present invention relates to a kind of patent retrieval method.

Background technology

Patent is as a kind of intellecture property; can bring abundant repayment to enterprise; therefore; each enterprise proposes patent protection to every innovation and creation that it is done one after another; but for the power of patenting; enterprise needs at first to determine whether its innovation and creation have novel; therefore; it often need be retrieved in various countries' patent database; whether tried to be the first with relatively more own innovation and creation and to apply for a patent by other people, but because most of keyword all has the speech identical or close with its semanteme, for avoiding omission; the retrieval personnel usually need keyword is considered comprehensively, have so reduced its recall precision.

Therefore, how to solve that shortcoming that prior art exists is real to have become the technical task that those skilled in the art need to be resolved hurrily.

Summary of the invention

The object of the present invention is to provide a kind of patent retrieval method, to improve retrieval personnel's recall precision.

In order to achieve the above object, the invention provides a kind of patent retrieval method, it comprises: 1) set up the expanding data storehouse that stores the expansion keyword that mates with each search key in advance; 2) the expansion keyword that mates according to the keyword that described expanding data storehouse is determined and the retrieval personnel import; 3) retrieve to obtain corresponding result for retrieval in specifying patent database according to the keyword and the described expansion keyword of retrieval personnel input; 4) described result for retrieval is shown.

Wherein, described matching way comprises semantic identical or close.

In sum, patent retrieval method of the present invention can reduce loss by the automatic expansion to the explanation of keyword, improves retrieval personnel's work efficiency.

Embodiment

Patent retrieval method of the present invention mainly may further comprise the steps:

1) set up the expanding data storehouse that stores the expansion keyword that mates with each search key in advance, for example, the expansion keyword that mates with LCD has LCDs etc., and wherein, described matching way comprises semantic identical or close.

2) the expansion keyword that mates according to the keyword that described expanding data storehouse is determined and the retrieval personnel import.

3) retrieve to obtain corresponding result for retrieval in specifying patent database according to the keyword and the described expansion keyword of retrieval personnel input.

4) described result for retrieval is shown.

In sum, patent retrieval method of the present invention can reduce loss by the automatic expansion to the explanation of keyword, improves retrieval personnel's work efficiency.
