Notice of Retraction: A method to evaluate the close degree of cooperation in research team: An empirical study

This paper defines the meaning of scientific research team, and selects the WISE Laboratory in Dalian University of Technology as a research team sample. By constructing a multi-value matrix and co-operation network, this paper apply social network analysis to analyze the close degree of cooperation in research team sample. This paper uses a method which contains six indicators — network structure, network density, compactness, average distance between points, cliques analysis and centrality analysis to evaluate the internal close degree of cooperation in research team. From the analysis results, authors find that these six indicators can better reflect and explain the close degree of cooperation in research team, and conclude the network characteristics in a research team with high internal close degree of cooperation.
