Method and system for retrieving key technologies in patents and literatures

Abstract

The invention provides a method and a system for retrieving key technologies in patents and literatures. The method comprises the following steps: acquiring a professional category to be retrieved; performing subject extraction on the literature and patent database according to the professional category to obtain a literature subject group and a patent subject group; performing patent intensity judgment on each subject in the patent subject group to obtain a score of each patent subject; performing literature intensity judgment on each topic in the literature topic group to obtain a score of each literature topic; and determining the key technology under the professional category according to the score of each patent theme and the score of each literature theme. The literatures and the patents are analyzed at the same time, and the key technology under the professional category is determined based on the scores of the patent and the literature subject, so that the key technology in one field can be found more comprehensively and more accurately, and the manual searching time is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of data retrieval, in particular to a method and system for retrieving key technologies in patents and documents. Background technique [0002] When scientific researchers or scientific workers want to understand the key technologies in a field, they need to search a large number of patents and documents, and then extract useful information from the data of documents and patents, but this often takes a lot of time. The patent application number is KR1020180094337 provides a patent analysis system, including: a patent data collector, used to collect patent data in the target technical field; evaluation index calculation unit, used to calculate patent evaluation indicators from the collected patent data (patent indicator); a SOM generating unit for generating a self-organizing map (SOM) from the collected patent data; and a visualization unit for visualizing the self-organizing map. The patent with the applic...
