Exploring Homophily in Research Collaboration: A Dynamic Centrality Analysis Approach

Homophily is the phenomenon of individuals seeking others who are similar to themselves. Homophily influences the formation of co-authorship networks. In our study, we measure the homophily of the authors based on their affiliation using the co-authorship network. The main contribution of our study is that we test homophily with a dynamic centrality analysis algorithm and find that homophily exists when we measure the authors’ degree within and outside their network. However, homophily does not exist when we use the dynamic centrality analysis algorithm for the same co-authorship network.
