Abstract: A new round of scientific and technological revolution is booming, and global competition in science and technology is increasingly encouraging. In the process of science and technology management, it is very important to scientifically judge the trend of industrial innovation and select key technology projects for layout. This paper elaborates the concept characteristics of the key core technology of the industrial chain process multi-source information such as scientific papers, projects, achievements and patents and establish the key technology recognition method based on LDA model. Then the multi-source scientific and technological information in AI is collected. The key technologies are forecasted based on the AI industrial chain analysis. It is timely, forward-looking and professional for government and enterprises strategic decision.

Key words: Industrial chain, Key core technologies, Multi-source information fusion, Technology topic automatic identification, Artificial intelligence(AI)
