基于SMS/MMS的移动社会网络行为建模与分析

Modeling and analysis on behavior of mobile social network based on SMS/MMS

为了有效地分析移动社会网络所具有的复杂网络特性,结合实际短信网络,研究基于短信/彩信(simple messaging service/multimedia messaging service,SMS/MMS)的移动社会网络行为建模方法及分析机制.首先,采用短信/彩信通信记录来构建社会关系图,并提出了基于社会关系图的移动社会网络行为分析机制.给出了移动社会网络行为分析的相关要素及其计算模型,采用社会网络分析的方法对出度、入度、用户朋友数、活跃度、亲密度、聚类系数等特征进行统计分析.实验结果表明:短信网络具有复杂网络的特性,活跃度能更好地刻画手机用户的移动社会网络行为.该方法能有效地用于评价移动社会网络中节点影响力的大小.

In order to evaluate the characteristics of complex network in mobile social networks,a modeling method and analytical mechanism on behavior of mobile social network were proposed based on simple messaging service /multimedia messaging service （SMS/MMS ）by combining the characteristics of real short message network. At first, social relationship graph was constructed using SMS/MMS. In addition, an analysis mechanism on behavior of mobile social network was presented based on the social relationship graph.The related factors of behavior analysis and their computing model were provided,and the method of social network analysis was used to count and analyze the characteristics of mobile social network,such as out-degree,in-degree,the number of friends,activity degree,intimacy degree,and clustering coefficient.Simulation results show that the real short message network has the characteristics of complex networks and that activity degree can be used to characterize the behavior of users in mobile social networks.The method can be used to evaluate the degree of nodes’influence in mobile social network.
