复杂网络社区分解中模块度的设计与分析

如何衡量复杂网络社区分割的好坏是近来研究的一个难点。Newman和Grivan提出了模块度的概念,是目前广泛接受的衡量标准,但是模块度在应用上存在自身难以客服的缺陷,因此改进模块度和定义新的衡量标准是近来研究的一个热点,我们提出了聚内系数和网络密度的概念,并论证了当社区结构差异较大时其能比模块度得到更加合理的划分。

Design and Analyse about Modularity in Community Detection of Complex Networks

It is a pivotal problem that how weights the effect of community detection of complex networks.Modularity put forward by Newman and Girvan is a index which accepted by people,but it has flaw that doesn,t overcome by itself.So,amelioration of modularity and finding new standard are important problems and popular topic on researching community detection.We put forward networks density and cohesion coefficient,it is proved that we can get better result when network configuration is evidently difference.
