Patent technology evolution analysis method and system

Abstract

The invention discloses a patent technology evolution analysis method and a patent technology evolution analysis system. The patent technology evolution analysis method comprises the following steps: S1, collecting patent data; S2, extracting patent information; S3, automatically partitioning technology development stages; S4, implementing technology evolution analysis; S5, implementing technology development tendency prediction. According to the patent technology evolution analysis method and the patent technology evolution analysis system, key information of patent information such as patent abstracts and application dates is extracted and used as a sample vectors of an ordered cluster, and the development stages of technology can be automatically partitioned by using an ordered cluster method objectively; the dynamic evolution process of the technology can be demonstrated, that is, the process of generation, development, upsurge till extinction of the technology; technology development tendency prediction is beneficial to implementation of technical strategic planning. The public can relatively conveniently and visibly understand the development process and the future tendency of the technology.

Description

technical field [0001] The present invention relates to the fields of text mining, machine learning and patent analysis, especially a patent technology evolution analysis method and system. Background technique [0002] The patent information set is currently the largest technical information set in the world, covering almost all technical achievements in application fields. Patents reflect inventions in specific technical fields, and previous studies have also pointed out that a considerable part of the information in patents is relatively new. The research results contained in patents have various values ​​such as business, industry, law and decision-making. If they are carefully analyzed, technical details and connections between technologies can be found, which can reveal business trends, inspire new industrial solutions, and help decision makers formulate investment policy. [0003] The rapid growth of patent documents promotes the development of advanced patent analy...

Problems solved by technology

Any technology has a budding period, a growth period, a maturity period, and a decline period. Therefore, the division of technology development cycles and the judgment of its development stages are important patent analysis tasks. The current analysis methods for time and space dimensions are far from satisfying our understanding of technology. Evolutionary processes and their characteristic needs
