摘　　要：随着移动社交网络平台的普及,个体通过移动设备迅速地接收、传播和交流信息,也使得真假不一的信息在这些平台上广泛传播,加剧了危机传播的频度和广度.基于正面信息源的影响力最大化,构建一个强关系与弱关系社交平台共演传播模型,以探索利用社交网络中的影响力个体来提升正面信息的传播效率.系统仿真试验发现,信息对个体影响度及弱关系社交层的信息传播效率在网络舆情共演过程中起着关键作用,增加影响力个体的比例可以减缓或抑制舆情进一步发酵,从而提升公共危机管理水平.With the popularity of mobile social networking platforms,individuals can rapidly receive,disseminate and communicate information through mobile devices.However,the widespread dissemination of misinformation on these platforms exacerbates the frequency and extent of crisis propagation.Based on the maximization of the influence of positive information sources,a co-performance of strong-ties and weak-ties social platform(CSWSP)dissemination model was constructed,and the use of influential individuals in social networks to improve the dissemination efficiency of positive information was explored.Through systematic simulation experiments,it was found that the influence of information on individuals and the efficiency of information dissemination in the weak-ties social layer play a crucial role in the process of online crisis co-performance.Increasing the proportion of influential individuals can mitigate or suppress further escalation of public sentiment,thus enhancing public crisis management.
