基于多层耦合网络的舆情传播控制研究

Research on Dissemination and Control of Public Opinion Based on Multilayer Coupled Network

为研究平台间信息交互对舆情传播以及舆情控制的影响,以微信和微博平台为例,利用多智能体建模方法和改进的SEIR模型,构建了包含"微信层-微博层-控制层"的多层耦合网络舆情传播和舆情控制模型。在Anylogic平台选取"湖北省红十字会物资使用情况引发质疑"舆情事件进行了仿真实验,分析了单/双平台、控制范围、控制力度、控制时间、平台间交互等因素的影响,研究了多平台互动传播下的媒体引导和政府干预策略。仿真实验表明,模型很好地刻画了微信、微博平台的信息传播特性,反映了舆情的跨平台传播效应。

In order to study the influence of information interaction between multi-platforms on the dissemination and control of public opinion,taking Wechat and Weibo for example,a public opinion communication and control model based on multi-layer coupled network including Wechat layer,Weibo layer and control layer is constructed using multi-agent modeling method and improved SEIR model.On Anylogic platform,a simulation experiment was conducted on the event that"the use of materials by the Hubei Red Cross Society raises doubts",and the effects factors such as single/dual platform,control range,control dynamics,control time and interaction between platforms were analyzed.The media guidance and government intervention strategies under multi-platform interactive communication is proposed.The simulation results show that the model describes the information transmission characteristics of Wechat and Weibo well,and reflects the cross-platform communication effect of public opinion.
