基于双层网络的学生用户通讯行为分析与建模

Analying and modeling of student communication behavior based on bilayer network

随着手机成为人们生活的必需品,手机用户通讯行为的研究越来越深入,但仍缺少将通讯行为与用户的真实社交亲密度相关联的研究。文中通过采集真实的学生用户通讯行为数据和用户与联系人的社交属性关系,应用复杂网络和行为动力学相关理论,以学生用户为节点、常用通讯行为为连边、社交亲密度为权重,建立了基于社交网络和通讯网络的叠加网络。结合学生用户群体特有的行为模式,深入分析了社交网络与通讯网络之间的联系,以及社交属性对通讯行为幂律分布的影响。在此基础上,针对学生群体的通讯行为特征,建立了星型网络拓扑结构下,基于亲密度的多用户交互通讯行为模型(Intimacy Interaction Model),此模型充分考虑了社交网络对通讯网络的影响,可与真实通讯数据进行较好的拟合。

The mobile communication is an important activity in human behavior,but there still lacks researches on the communication behavior combining with user social intimacy. Communication data marked with social properties by user themselves are obtained from a group of university students. Based on the theory of human dynamics and complex networks,a bilayer network of social behavior and communication behavior is established by using student users as nodes,common communication as links and social intimacy as weights. Considering student specific behavior patterns,the connections between social network and communication network,and impacts of the social property on the power law distribution of the communication behavior are analyzed. On the star network topologies,an interactive model of communication based on intimacy is established. The model is closer to the student real communication behavior and fits the actual data well.
