Collaboration and Friendship of Scholars: A Dual Metwork Analysis

摘要

In this study, we analyze the dual network of scholars' co-authorship and online friendship. We conduct comparisons of these two networks in the field of scientometrics. Using co-authorship data of publications and following data on ResearchGate, we extract the co-authorship network and online friendship network, respectively. The results reveal several topological differences between these two networks. The edges of co-authorship network are more decentralized than the online friendship network. Moreover, the co-authorship network has a clear community structure, while the online friendship network has clustered communities. However, the two networks have a strong internal relationship. Specifically, the co-authorship intensity has an impact on the formation of social relations. The academic social network promotes the integration of and scholarly communication among academic communities.
