摘要:  

摘要: 寻找复杂网络中的社团结构对于理解复杂网络的结构和功能有十分重要的意义。本文对节点间的依赖程度进行分析,给出节点是否归属社团的新标准。从节点强度最大的节点开始根据节点间的依赖程度寻找一个初始社团,再依据一些定量条件增加节点扩展社团,由于仅需要用到节点的局部信息,时间复杂度达到了线性。将该算法应用于经典的Zachary网络,验证了其有效性。

Abstract:  

 Abstract:  Detecting community structure in complex networks is significant in understanding the structures and functions of networks. The dependence degree of two nodes is analyzed, and a new standard is found for whether a node is belonging to the community. An initial community is first constructed from a node with maximal node strength and its neighbors which satisfying the dependence degree quantitative condition, then the initial community is expanded by adding nodes according to some quantitative conditions. Only local information of nodes is need to use, so the time complexity is a linear complexity. It is applied to the classic Zachary network to verify the validity.
