Complete patent retrieval system

Abstract

The invention discloses a complete patent retrieval system. The complete patent retrieval system is characterized by comprising a first retrieval type storage unit; a first search unit; a complete search sample storage unit; a recall ratio calculation unit; a recall ratio comparison unit used for comparing a ratio obtained by the recall ratio calculation unit with a threshold value; an accuracy rate calculation unit used for performing spot check on literature from a retrieval result set to form a spot check literature set when the ratio obtained by the recall ratio calculation unit is greaterthan a threshold value, and comparing the number of literature related to the retrieval strategy in the spot check literature set with the number of literature in the spot check literature set to obtain a ratio; an accuracy comparison unit used for comparing the ratio obtained by the accuracy calculation unit with a threshold value; and an output unit used for outputting a retrieval result set when the ratio obtained by the accuracy calculation unit is greater than a threshold value. According to the method, a comprehensive and accurate retrieval result can be obtained, accurate patent analysis can be obtained, and decision errors are reduced.

Description

technical field [0001] The invention relates to a retrieval system, in particular to a patent retrieval system. Background technique [0002] With the increasingly fierce technological competition in the world, companies from various countries have carried out patent strategy research, and the core is patent analysis, which is to analyze, process and combine a large amount of fragmentary patent information in patent specifications and patent gazettes, and use statistical methods And skills to transform this information into competitive intelligence with overall overview and forecasting functions, so as to provide reference for decision-making in the development of technology, products and services of enterprises. Patent analysis is not only a prerequisite for companies to compete for patents, but also provides useful information for companies to develop their technology strategies and evaluate competitors. Therefore, patent analysis is a unique and practical analysis method...

At present, people can search on the search platform by inputting the search formula and get the search results. However, the existing search platform lacks a comprehensive and accurate evaluation of the search results, which may cause inaccurate patent analysis and waste time. cause wrong decision
