| With the rapid development of contemporary science and technology,the speed of technology renewal is increasing rapidly,and competition within and outside the industry has also intensified.This series of changes has higher requirements for companies to mastering the industry's core technologies and technological innovation.But technological innovation cannot be separated from technology foresight.As a knowledge carrier with rich information,patents are rich in technology,products,economic and legal information.The quantity and quality of patents have become an important indicator to measure the competitiveness of a country or an industry's science and technology.By tapping patent information,the industry and industry's core technology and technology development prospects can be obtained.Therefore,it is important to study how to tap core technology information from a large number of patents and explore the development status and development path of technology,look for technical development vacancies.This will have important guiding significance for enterprises to maintain their core competitiveness.This article takes the patent text as the research object,proposes a patent similarity calculation method and technology mining method system based on the SAO structure,and combines qualitative research and quantitative research methods.This method solves three problem which is mining the core technology and ananlysis the relationship between technologies and Forecasting technology trends.Firstly,the patent similarity calculation model is constructed with patent abstracts,independent claims,and IPC classification numbers,and verified the validity of the model through patent datas of industrial robot.A patent network map and a patent map are constructed based on the patent similarity matrix,and the technology development path is analyzed combining with the TRIZ theory.Then the technology hotspots,technology transfer processes,and future development technologies are analyzed.Secondly,based on the characteristics of SAO structure,this paper proposes a SAO chain technical morphology analysis method.This method builds a technical hierarchical structure of SAO chain and analyzes the correlation between technologies by combining SAO semantic similarity calculation methods.Finally,based on the research foundation of the Guangzhou Philosophy and Social Sciences "13th Five-Year Plan"(2018GZYB16)and the Science and Technology Revolution and Technology Foresight Think Tank(X2GSN4160224)project,the technology mining method system of this paper is applied to the field of industrial robots,the core technology,development path,technology layered structure and technology development trend are excavated.Which provide theoretical guidance for the technology research and technology prediction of related companies and research institutes. |
