[目的/意义]从多角度分析网络辟谣信息主体的类型、相互关系、社区结构和辟谣信息传播效果,有助于发现关键的辟谣信息主体和有效的网络辟谣信息扩散模式,对于加强突发公共卫生事件期间的舆情引导及维护社会稳定具有重要作用。[方法/过程]选取新冠肺炎疫情期间"双黄连"辟谣事件,通过Neo4j构建辟谣主体关系网络,利用Louvain社区发现算法划分网络社区;通过内容分析和回归分析对网络辟谣信息主体的内容特征和辟谣策略进行比较和分析,并构建"主体-内容"二模网络,以分析不同信息主体和网络社区如何推动社交媒体中的辟谣信息传播以及行之有效的辟谣方式和辟谣策略。[结果/结论]研究结果发现,政府和大众媒体是网络辟谣中的主要行为者。政府最普遍使用反驳谣言的策略,大众媒体则与之相反。内容特征对辟谣信息传播效果具有不同的影响。
