Modularity matrix of networks and the measure of community structure
网络的模块矩阵及其社团结构指标

The relationships between positive (negative) eigenspectrums and the structure properties of community (anti-community) of complex networks are investigated,and some corresponding definitions are given. By using the multieigenspectrums of modularity matrix of networks,a kind of structural centrality measure called the community centrality,is introduced. This individual centrality measure describes the strength that the individual adheres to the corresponding community. The measure is illustrated and compare...
