Method for creating index lexical item as well as data retrieval method and system

Abstract

The invention discloses a method for generating a retrieve lemma, a data retrieval method and a data retrieval system, wherein, the method for generating the retrieve lemma comprises the following steps: A. related vocabularies are inquired according to a lemma of an original subject, and a related vocabulary recommendation table is established; B. a database is inquired by utilization of the related vocabulary recommendation table, and a literature summary is retrieved; C. text mining of the retrieved literature summary is performed, and a recommended lemma which is matched with the content of a key word is obtained; D. the recommended lemma is inserted into the related vocabulary recommendation table to form a key word recommendation table. The method for generating the retrieve lemma, the data retrieval method and the data retrieval system mainly apply the automatic text mining technique and the statistical technique and combine a little manual correction to obtain the overall key word recommendation table and utilize the table for retrieval of the database.

Description

technical field [0001] The present invention relates to database automatic retrieval technology, in particular to a method for generating retrieval entries and a data retrieval method and system. Background technique [0002] Usually, patent documents are searched through the patent document database retrieval system provided on the website of the State Intellectual Property Office (http: / / www.sipo.gov.cn / sipo / zljs / ). When using the patent literature database retrieval system for patent retrieval, you can enter a relational expression in the retrieval entry to search. Although search access may not be a problem for professional searchers, it is not easy for non-professional searchers to achieve "complete" and "accurate" patent searches. [0003] The existing methods to achieve this goal are: [0004] (1) According to the limited keyword list provided by the search topic, set the search relationship as accurate as possible, and search the literature database to obtain the p...

Problems solved by technology

This is a very complex and highly specialized job and to be completed in a short period of time requires professional level patent search skills and subject matter expertise

[0006] The simple information given by the search topic cannot fully reflect the distribution of its keywords, so the search results obtained are usually not accurate and comprehensive.

However, professional patent search personnel need to manually read a large number of documents when searching the patent literature database, which is time-consuming, labor-intensive, long-term search cycle, and low efficiency; for non-professional patent search personnel, professional training is also required to learn and "patent search" subject” related knowledge, further prolonging the patent search time
