The emerging trend detection of the discipline area themes is an important topic paid attention to by information re search personnel and scientific research management and decisionmaking personnel together. It＇ s also the challenge faced by infor mation research and one of the key problems to be solved. Many researchers both at home and abroad have done a lot of research work in the emerging trend detection methods of the discipline area themes. Based on the extensive survey of the existing detection methods, this article analyzes the main problems in the emerging trend detection methods of the subject discipline area themes, and in accordance with these problems, proposes to use the method of combining keyword lifecycle with weighted direct citation network analysis to detect the emerging trend of the discipline area themes. The article also expatiates on the key links and technologies of the method.
