Ineffective scientific knowledge and false news will have a serious negative impact on social stability and disrupt social order during the outbreak of epidemics. Therefore, it is very important to build an effective reversal model of online rumor propagation to control the spread of online rumors and reduce its negative impact.[Method/process] The research adopted the theory of scientific knowledge level and the strategy of online rumors reputation, and constructed the SCNDR online rumor reversal model based on SIR model. The Anylogic software was adopted to simulate the SCNDR model, and the sensitivity analysis of the parameters of the model was carried out.[Result/conclusion] The SCNDR model proposed in this study effectively simulates the reversal process of online rumors during public health emergencies. The key factors affecting the reversal efficiency of online rumors are the penetration rate of users' scientific knowledge level, the public time of official information and the conversion efficiency of credulous users. 网络谣言突发公共卫生事件逆转模型系统仿真期刊：图书情报工作分类：图书馆学、情报学 >> 情报学引用： ChinaXiv:202304.00483 (或此版本 ChinaXiv:202304.00483V1 ) doi:10.12074/202304.00483 CSTR:32003.36.ChinaXiv.202304.00483.V1 推荐引用方式：王晰巍,李玥琪,邱程程,胡欢.(2023).突发公共卫生事件下网络谣言传播逆转模型及仿真研究.图书情报工作.[ChinaXiv:202304.00483] 版本历史 [V1] 2023-04-01 16:02:56 ChinaXiv:202304.00483V1 下载全文
