Identification of Key Core Technologies and Analysis of Competitive Situation Based on xDeepFM Model:Take the ICT Equipment Manufacturing Industry as an Example
[Research purpose]Based on the"inversion"scenario,this paper identifies the key core technologies of the telecommunica-tion industry to explore the power source of the inversion and the evolution of its competitive situation.[Research method]The study sorts out the definitions,characteristics and identification methods of key core technologies,selects one million patents applied globally since 1984 by four communication equipment companies,Nokia,Ericsson,Huawei and ZTE,as a sample,constructs a deep prediction neural network model(xDeepFM)based on factorization machine,and realizes key core technology identification and competitive situa-tion analysis.[Research conclusion]The identification model built based on xDeepFM can effectively identify and evaluate key core technologies in massive patent data.Through thematic analysis of the identified key core technologies,the competition situation analysis of key core technologies in the communications industry is described and evaluated to provide intelligence support for identifying the charac-teristics of key core technologies and win the battle against key core technologies.
