The Detection And Appraisal Of Research Teams Based On Social Network Analysis

Since 40's in 20th century, along with the complexity and profession of science research the importance of science cooperation have been highlighting day by day. In the natural science realm, the cooperation of research teams which across institution and region become the main research mode. Recognizing and appraising research teams has important theory and practice meaning. In order to more useful develop and propel research work, the science researchers have to understand the network structure characteristics, the process of knowledge swap and produce, and various factors that impact research team producesThis paper applies methods such as social network analysis, the information gauging, comparative analysis, information to deduce etc to carry on a thorough study to the detection and appraisal of research team. This paper makes use of the various theory and network metrics of social network analysis and digs out existing large-scale and invisible research team in the co-author network, provide a new way of thinking and foundation for other searches of the related realm.The full text can be divided into four parts:Part 1, discusses the search back ground of research team, the purpose of the paper, and the meaning, context, method of the study.Part 2, review domestic and international search fruit concerning research team, include team detection, team appraisal, team impact factor and social network analysis four fractions. The social network analysis part concretely introduces the foundation theory, generalizes the applied realm of social network analysis, discusses how to build co-author network.Part 3, in this chapter, writer apply related theory and technique of social network analysis to the research of detection and appraisal of the research group. The connection between the network structure, characteristic and team output-input ratio of research team have been found, and effect factors of team performance have been recognized. Mainly include a typical model of team network structure, the detection of research teams and the impact factors of research teams'performance three fractions.Part 4, aim at the various network factors which impact team performance writer put forward several suggestions to promote the performance of research teams.
