Centrality Analysis of BBS Reply Networks

摘要

As an important concept in the field of social network, centrality is usually applied to study individual behavior and group behavior of complex networks. In order to analyze nodes centrality of two BBS reply networks, we investigated degree and between ness of nodes and counted the correlation coefficient of degree and average between ness. On the basis of the degree centrality and between ness centrality, the network centralization was especially analyzed. Then, we addressed central nodes and compared network centralization of two BBS reply networks. It is shown that network centralization varies obviously when central nodes are removed, which implies that central nodes have high influence and power in complex networks.
