Abstract

A patent data retrieval system comprises: a rule library for storing key word rule extracted from article, an extraction key word module for extracting key word from a patent document input by searching staff according to the rule in the rule library, a searching module for retrieval in the patent database according to the extracted key work to find the patent document associated with the patent file, and a display module for displaying the patent document as a reference to the searching staff, so that associated or similar technical document can be found through the technique of determining file input by searching staff, which helps the searching staff get acknowledge of development level of relevant technology.

Description

Patent data retrieval system

Technical field

The present invention relates to a kind of patent data retrieval system.

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 innovation and creation of oneself relatively and to apply for a patent by other people; therefore the retrieval personnel often needed to limit keyword before retrieval; and it at first needs to understand corresponding techniques when determining keyword; need spend the more time in early stage with assisted retrieval work, the retrieval rate that therefore how to improve existing retrieval personnel's search method raising retrieval personnel has become the technical task that those skilled in the art need to be resolved hurrily in fact.

Summary of the invention

The object of the present invention is to provide a kind of patent data retrieval system, retrieve the correlation technique document that it needs to help the retrieval personnel.

In order to achieve the above object, the invention provides a kind of patent data retrieval system, it comprises: be used for storing from article extract the keyword rule rule base, be used for according to the rule in the described rule base from the patent file of retrieval personnel input extract keyword extraction keyword module, be used in patent database, retrieving to retrieve with the retrieval module of the relevant patent documentation of described patent file, to be used for described patent documentation is shown display module for described retrieval personnel reference according to the keyword that is extracted.

In sum, the relevant or close technical literature that patent data retrieval system of the present invention can fall in the patent database automatically by the technology of the document of deterministic retrieval personnel input is retrieved out, helps the retrieval personnel to understand the development of technologies level.

Embodiment

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

1) rule base is used for storing from article and extracts the keyword rule, and for example, described rule base comprises extract keyword from article title, extracts keyword etc. from article abstract.

2) extract the keyword module, be used for extracting keyword according to the rule in the described rule base from the patent file that the retrieval personnel import, the patent file of retrieval personnel input can be the document of downloading from the Internet, also direct document by the keyboard input.

3) retrieval module is used for retrieving in patent database to retrieve the relevant patent documentation with described patent file according to the keyword that is extracted.

4) display module is used for described patent documentation is shown the reference for described retrieval personnel.

In sum, patent data retrieval system of the present invention can be retrieved out with the relevant or close technical literature in the patent database by the technology of the document of deterministic retrieval personnel input automatically, helps the retrieval personnel to understand the development of technologies level.

Claims

1. patent data retrieval system is characterized in that comprising:

Rule base is used for storing from article and extracts the keyword rule;

Extract the keyword module, be used for extracting keyword from the patent file that the retrieval personnel import according to the rule in the described rule base;
