考虑群组结构的在线社交网络竞争性舆情信息传播模型研究

Research on competitive public opinion information dissemination model in online social networks considering group structure

针对在线社交网络中竞争性舆情信息同时传播的问题,在无标度网络的基础上引入群组结构,构建竞争性舆情信息传播模型,考虑舆情信息内容、用户亲密度、社会强化效应因素并进行仿真研究。仿真结果表明,引入群组结构的无标度网络充分契合了在线社交网络的复杂性质;群组数量、群组规模、用户亲密度、社会强化效应对竞争性舆情信息的传播有不同的促进作用;控制舆情信息内容的重要性与模糊度可有效调控竞争性舆情信息的传播与扩散。

Aiming at the problem of simultaneous dissemination of competitive public opinion information in online social networks,this paper introduced group structure on the basis of scale-free network,constructed a competitive public opinion information dissemination model,taken into account the content of public opinion information,intimacy of friends,and social strengthening effects to conduct simulation research.The simulation results show that the introduction of group structure of scale-free network fully fits the complex nature of online social networks.The number of groups,group size,intimacy of friends,and social strengthening effects have different promoting effects on the dissemination of competitive public opinion information.Controlling the importance and ambiguity of the content of public opinion information can effectively control the dissemination and diffusion of competitive public opinion information.
