摘要/Abstract

摘要： 微博聚集了大量的用户群体,社区结构是微博网络的重要特征。为了探索微博网络的社区结构对舆论话题传播的影响规律,分析了微博用户选择关注对象的心理,基于此提出了微博社区网络的构造模型,该模型可以通过社区因子调节微博网络的社区结构特征。实验中验证了社区因子对微博网络社区结构的影响,基于SIR模型仿真分析了传播源节点和社区因子对微博舆论话题传播的影响机理。仿真结果表明,与名人效应相比,网络的社区结构对微博话题的传播具有一定的抑制作用。通过twitter实例数据对部分结论进行了验证。

Abstract: Micro-blog gathers a large number of users, and community structure is a typical feature of Micro-blog network. In order to explore the influence of community structure on the opinion topic propagation of Micro-blog, users' psychology was analyzed for selecting their followees, and a model for constructing Micro-blog network was proposed which could modify community structure of network with a community factor. Experiments testify the effect of the community factor on micro-blog network structure, and use a SIR model to analyze the influence of different topic source nodes and community factors on the topic propagation of simulated networks. The result shows that community structure has a negative effect on the topic propagation compared with the effect of celebrities in the Micro-blog. An example data from twitter testifies some conclusions.

Key words: micro-blog, topic propagation, community structure, network modeling
