【目的/意义】近年来微信已成为民众社交的首要平台,同时也逐渐成为谣言传播的主阵地,但目前针对微信谣言传播的研究尚不多见。【方法/过程】将微信网络划分为朋友圈网络、群网络和公众用户网络,生成了微信谣言传播加权有向三层网络,在此网络基础上构建了基于兴趣衰减效应的线性阈值谣言传播模型,并利用多主体仿真平台Netlogo对该模型进行仿真。【结果/结论】研究发现,微信群的存在改变了个人用户网络节点的度分布,且导致当节点信任度较低时微信网络比微博类网络更有利于谣言的传播;节点信任度与谣言的传播力度显著正相关;增大谣言传播阈值和减小谣言传播兴趣值,能有效抑制谣言的传播。
Purpose / Significance WeChat has become the primary platform for people’s social networking in recent years and has gradually become the main front for the spread of rumors. However, the research on the spread of rumors is still rare. 【Method / Procedure】 WeChat network is divided into circle of friends, group network and public user network. Wechat-rumor propagation weighted-directed three-layer network is generated. Based on this network, a linear threshold rumor propagation model based on interest decay effect is constructed , And use the multi-agent simulation platform Netlogo to simulate the model. 【Result】 The research shows that the existence of WeChat groups changes the degree distribution of individual user network nodes, and leads to the spread of rumors more favorable than the micro-blog network when the node trust is low. The node trust and rumor . The increase of the rumor transmission threshold and the reduction of the rumor transmission interest value can effectively suppress the spread of rumors.
