Introduction:
China has entered an important period of alternating between the 13th Five-Year Plan and the 14th Five-Year Plan. The huge demand for source innovation from various fields, such as economic and social development and national security, has been released, and it is urgent to improve the energy efficiency of the transformation of the achievements of the innovation system. The process of innovation greatly drives the generation and accumulation of corresponding scientific and technological text data, and implies important knowledge and competitive intelligence such as core technology, key elements and potential cooperation opportunities. In the environment of big data, how to extract the technical topics from the perspective of machine learning, abstract complex relationships, and then explore these hidden knowledge, is becoming one of the important research issues that the academic and industrial circles pay attention to. Based on recent related studies, the speaker introduces the basic concepts and methods of topic model and word embedding, exchanges on technical topic identification and topic network analysis, and discusses the future research topics in related fields.
