摘要
网络热搜话题具有传播扩散现象,当前对于网络热搜话题的研究主要集中在传播效果评估、传播趋势预测、社会影响评价以及舆论引导等方面,而对于网络热搜话题的研究未能揭示传播动力学参数对于传播过程的影响。文中采用SEIR模型构建了网络热搜话题传播动力学模型,分析研究了网络平均度、不信任概率、接触后立即传播概率、感染率、治愈率、复发率等影响因素对模型的影响。
Online hot search topics have the phenomenon of dissemination and diffusion.The current research on online hot search topics mainly focuses on the evaluation of communication effects,prediction of communication trends,social impact evaluation and public opinion guidance,while the research on online hot search topics fails to reveal the impact of communication dynamics parameters on the communication process.In this paper,the SEIR model is used to construct the dynamic model of the online hot search topic propagation,and the influence of the network average degree,the distrust probability,the immediate transmission probability after contact,the infection rate,the cure rate and the recurrence rate on the model are analyzed.
