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

Embodiment Construction

[0066] The present invention is described below in conjunction with accompanying drawing and specific embodiment:

[0067] The design idea of ​​the analysis method of the present invention is as follows: first obtain patent data from the patent website; store the obtained data in the database; extract the field information required for subsequent steps from the database; establish a vector space model of patent data; use ordered clustering The method automatically divides the development stages of technologies; calculates the hot technologies in each stage, discovers the process of the disappearance of backward technologies and the emergence of innovative technologies; draws the change curve of the number of patents, and predicts the trend of technological development.

[0068] A patent technology evolution analysis method, comprising the following steps:

[0069] S1: Patent data collection:

[0070] According to the set time interval and keywords, use web crawler technology ...

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...
