Research On Network Emotion Transmission Based On SIRS Model In The Event Of Emergency

In the recent years,with the Internet rapid development,the number of Internet users has been more and more,which leads to a large number of public opinion information that filled in the cyberspace,the public opinion information profoundly affects the psychology and behavior of Internet users,especially the network frequent emergencies,which causes the people who learn through the network public opinion,or as a result of the affected by positive,or negative emotions,these feelings under the influence of the networking groups,is easy to produce polarization,which affects the netizen the behavior of the individual,if the mood of negative polarization,with no guidance,will cause serious social consequences.Therefore,by holding the emotion to Internet users,targeted to take corresponding intervention strategies,is of great significance for the enterprises and institutions and the government.Based on SIRS model,this paper analyzes the key influence factor in the spread of the emotion,with 2016 Wei ze-xi network events,for example,collecting relevant data,using Gephi first generation communication network model,using Netlogo simulation software,python language on the model experiment,by adopting the combination of emotion and mind of mining index,find out the key nodes,you can then select target immune strategy is used.The concrete research content includes the following three aspects:1?Through the elaboration of information dissemination mechanism,analysis of information and emotions of the relationship between each other,which leads to the emotions and emotional transmission mechanism,mechanism of integration between the two.Take graph modeling method,based on the social network,data collection for a weibo,emotional communication network is established.2?Based on the SIRS model,and then according to the characteristics of the social network,to join the birth rate and loss rate of immune two parameters,and the stability of the model is proved with lyapunov stability principle.By changing the parameter values,to observe the influence of percentage of infected people,finally determine the immunity and immune loss rate are the key factors influencing the number of infected people.3?According to the conclusion of the fourth chapter,the know immunity andimmune loss rate are the key factors that influence the spread of emotional effect,the fifth chapter use the corresponding immune strategy which is immune to the nodes in the network,by comparing three kinds of immunization strategy and an improved immune strategy,it is concluded that the target immunization strategy is the best.Finally adopts the method of combining emotion index and centricity index,dig out key nodes,it is concluded that the immune effect of contrast figure.
