Abstract： [Purpose/significance] Identifying the trajectory of development is of great importance to scientific and technological innovations. However, existing methods such as expert interviews and citation analysis cannot meet the current situation of the explosive growth of literature. In response to this problem, this paper proposes a new identification method of filed development trajectory. [Method/process] This method identifies the research topics and related scholars by using Kmeans ++ and spectral clustering algorithms with the keyword-scholar matrix, calculates the correlation between different topics, and finally visualizes the trajectory of developmen. [Result/conclusion] Through the empirical analysis of the field of artificial intelligence, the results show that the method can effectively reflect the evolution of the topic of field research, help researchers quickly locate popular research topics and focuses, and enrich the research methods related to the trajectory of field development.

Abstract： [Purpose/significance] Technology fusion is the driving force of new industries' formation and development. While the knowledge fusion is the prerequisite of technology convergence, it is of great significance in guiding the formation and development of new industries.[Method/process] Firstly, this paper built a theoretical model which using the citation network to characterize the knowledge fusion process based on the existing research. Then, based on the characteristics of paper citation network in each stage of knowledge fusion, the paper introduced a verification method. Finally, it conducted an empirical analysis in the field of bio-information technology.[Result/conclusion] The results of empirical analysis in the field of biological information show the validity of the theoretical model. Therefore, It can be deemed as a new method on studying the knowledge fusion.
