社交网络下的谣言扩散与控制研究

Research on the Diffusion and Control of Rumors under Social Networks

基于危机生命周期提出了网络谣言扩散模式的5个阶段,分析了网络谣言扩散的循环过程;基于社交网络节点的星形传播结构以及节点的集团性,提出了谣言控制策略——社区识别,即通过求节点的余弦相似度划分社区,同时确定初始聚类节点选取的原则,据此提出关键节点的控制策略;根据社交网络的拓扑结构,指出对于有较大出度和入度的节点进行控制至关重要。

This paper puts forward the five stages of network rumor diffusion model based on crisis life cycle, and analyzes the circulation process of network rumors spread; and basing on the star communication structure of the social network nodes and nodes＇ group nature, puts forward the rumor control strategy, community identification, that is to divides communities through calculating the nodes＇ cosine similarity, at the same time, to determine the principles of selecting the initial cluster nodes, and then to put forward the control strategy of key nodes; and according to the topological structure of social network, points out that controlling the nodes with greater out-degrees and greater in-degree is very important.
