Fecha de publicación: 26/10/2022 Fuente: Wipo "BigData" The present invention provides a technology maturity judgment method and system based on science and technology big data. The method comprises establishing a database, an algorithm library and an index library, and further comprises the following steps: performing data retrieval in the database; performing data calculation and organization on a retrieval result; performing regression calculation on organized data to obtain a technical maturity index; obtaining a judgment conclusion according to the technical maturity index. The present invention is mainly based on the patent analysis method, and assisted by technical big data analysis of papers, projects and the like, technical points are placed in a technology cluster associated with the technology to perform comprehensive analysis by multi-dimensional evaluation indexes and algorithm. Mapping between science and technology big data indexes and technology maturity is established, automatic judgment is achieved, and the method is different from a traditional expert review method.
