基于谣言传播网络模型的重要角色发现研究

Research on Important Role Discovery Based on Rumor Propagation Network Model

当今高速发展的网络信息时代减少或避免虚假信息传播尤为重要。在谣言传播模型的基础上引入了消息可信度和网络模型重要角色,提出了在消息传播模型中采用删除法等重要性指标的重要角色的识别与发现方法,并与加权介数做比较,利用大量的新浪微博数据进行统计与分析。该方法重构了微博传播模型,揭示了消息传播的演化机理,为消息传播的有效控制提供依据。

It is important to reduce or avoid the spread of false information in this digital information era. This research, by adding news credibility and the important role network model to rumor spreading model, puts forward ways to identify the important role of the deletion method and the importance index of the model in the news spread, compares them with the weighted betweenness, and make statistics and analysis of sina micro - blog data. The results show that the model reconstructs the main structural features of the micro - blog communica-tion model, reveals the evolution mechanism of the message propagation, and provides the basis for the effective control of the message prop-agation .
