电话社会网络结构的实证分析

Empirical analysis on topological structure of telephone call social networks

根据城市中的电话通话记录建立了一个大型的社会网络,研究了这个网络的有关结构特性.网络呈现了与相关社会网络相似的特性,如度分布的幂律特性、小世界效应、非平凡聚集或网络传递的特点等,同时该网络也表现出与其他社会网络不同的特性,如度的异向匹配.通过给边赋予权重,分析了网络在加权情况下的一些静态结构性质,其中,包括点强度分布、强度相关性及群聚系数等.

A social network is constructed based on local telephone call records in a city and the topological characteristics of the network are measured. This social network shows some same characteristics as those of other social networks, such as power law of degree distribution, small world effect, non-trivial clustering or network transitivity, and it also shows the property of assortative mixing which is different from other social networks. Then, by endowing the edge valus, the strength of vertex distribution, degree correlation and clustering coefficient of weighted network are analyzed.
