Research Method And Application Of Technology Development Based On Patent Knowledge Map

With the development of emerging technologies such as Industry 4.0.,Big Data and cloud computing,more and more countries and enterprises recognize the importance of promoting economic and technological transformation.Therefore,how to grasp the development information of an industry,and seize the opportunities of the future become a concern.As the important resources about technology,product,economic and legal information,patent is the knowledge carrier of the dissemination of scientific and technological innovation.Patent has become an important indicator to measure the competitiveness of a country or industry,and the invention and creation of science and technology become the core problem of strengthening the national innovation ability and improving the competitive advantage of the enterprise.Thus,it has important guiding significance for the enterprise to explore how to keep the core competitiveness to study how to dig out the technical information and form the knowledge map from the patent.It can identify the core patents,explore the development status and the path of the technology,and find the development opportunity.At present,the domestic and foreign research on the patent knowledge map is mostly based on the quantitative analysis of the patent data,which contains insufficient technical information.Based on the analysis of patent literature,this paper presents the research methods for technology development based on patent knowledge map combined with qualitative analysis and quantitative analysis.A patent similarity calculation method based on SAO-VSM model is proposed.Firstly,the SAO structure is extracted from the patent abstract,and calculates the similarity between the SAO structures to obtain the SAO-based patent similarity.Next,select the technical key words to accurately extract the patent instructions text structure to build VSM model,and calculate the VSM-based patent similarity by using the similarity coefficient.Then we obtain the patent similarity in this paper with SAO-VSM model,and verifies the validity of the method through the patent data about RFID industry.Furthermore,through the quantitative analysis of the external features of the patent,the patent quality evaluation method is proposed to constitute the research methods for technology development based on patent knowledge map.It is applied to the visualization and analysis of knowledge map,and this paper proves the validity of patent quality to the identification of valuable anomaly patents through experiments.Moreover,the method of this paper is used in the research for technology development of intelligent home industry.Through the analysis of core patents in patent networks at different stages of development,this paper reveals the technology development of smart home industry.And by analyzing the abnormal patents and vacancies in patent map,this paper points out the direction and opportunities for future development.Finally,this paper puts forward the management implications,existing problems and future research directions.
