Research On Wechat Information Propagation Mechanism Based On Infectious Disease Model

With the development of Internet technology,mobile social networks shorten the distance between real-life information exchange.As a communication channel for information exchange,mobile social network changes the way people exchange information,becomes indispensable media tools.The current WeChat is the most frequently used,the most influential mobile social software,in the social network information dissemination occupy a unique position.As a strong relationship between mobile social software,its real-time transmission,content miniaturization,spread fast and spread a wide range of features,so that information dissemination is difficult to control and other unpredictable characteristics of social stability and development there are some hidden dangers.Therefore,it is of great practical significance to analyze and study the micro-communication process,master the law of micro-information transmission and the mechanism of communication.In the process of researching micro-information communication,the traditional propagation model and research method can not describe the interaction between individuals,and can not observe the macroscopic evolution process.In this paper,the use of complex network and infectious disease model,the micro-social network communication characteristics and information dissemination mechanism of the analysis of similar information dissemination process in-depth study and simulation of its occurrence process,build WeChat information dissemination mathematical model,Or control micro-information dissemination related strategies.The main contents of this paper are as follows:Based on its propagation characteristics and propagation pattern,the SIRS model with overlapping relational network is constructed on the basis of SIR model.And calculate the propagation threshold and the equilibrium point.The influence of the parameters on the propagation of micro-information is analyzed by using the event reattention rate and the information shielding rate to study the propagation state of the information in the WeChat platform.The simulation results show that the propagation model is more consistent with the characteristics of micro-communication,which can reflect the influence of micro-information dissemination related factors on social network information dissemination.By changing the corresponding parameters,in the virtual social network can effectively control the WeChat information dissemination process.In view of the above-mentioned micro-information transmission SIRS model,considering the influence of multi-stage influence and the non-uniform influence of information on the influence of information transmission and propagation threshold on social network,the information conversion rate conversion rate,active removal rate and passive removal rate The The influence phase is divided into multiple progressive effects by a state,which further improves the micro-information propagation model.Based on the qualitative theory of differential equations,the stability and propagation characteristics of the model are analyzed.In the simulation experiment,the concept of propagation time scale is introduced,and the simulation comparison is made from the aspects of information transmission source,network density and network scale.The results show that the information propagation speed is faster and the influence range is larger in the scaleless network.At the same time,it is better to reduce the influence of information transmission by setting reasonable threshold.The model is more consistent with the propagation law of information in real life.
