Research On The Communication Mechanism And Guidance Strategy Of Public Opinion In Mobile Environment

In 2018,CNNIC released the 42nd report on the use of Internet in China.As of June 2018,the scale of Internet users in China reached 802 million,with the penetration rate of 57.7%.The scale of mobile phone users in China reached 788 million,and the proportion of Internet users accessing the Internet through mobile phones reached 98.3%^[1].This shows that the era of mobile Internet has come,and the way people exchange and share information is changing:netizens are using mobile tools such as smartphones and Ipad to participate in public social management and network public opinion dissemination.At the same time,it is more convenient for netizens to express their opinions in the mobile environment,with greater influence and wider range of dissemination of opinions.However,the social harm caused by false information is stronger.Therefore,it is of great significance to study public opinion in mobile environment.In this paper,the dissemination mechanism of network public opinion in mobile environment is discussed in depth,and the dissemination of public opinion in mobile environment is studied from group and individual perspectives,so as to build a model of public opinion dissemination and seek strategies to guide and manage network public opinion in mobile environment.Specifically,the main experimental contents are as follows:Firstly,the characteristics of public opinion transmission in mobile environment are analyzed based on group perspective,and the evolution model of network public opinion based on group perspective is constructed.Through numerical simulation experiments,the influence of group interaction threshold,derivation rate of new topics,degree of social inclusion and intensity of network public opinion on its evolution law are analyzed.The experimental results show that the model has wide applicability.When the interaction threshold is large,the evolution of public opinion is easier to carry out;the greater the probability of netizens creating new topics,the longer the relaxation time of public opinion evolution.Secondly,from the individual perspective,combined with the SEIR model of infectious diseases,considering the differences of individual transmission patterns in mobile environment and the different degree of individual influence by public opinion,taking Weixin Public Opinion Communication as an example,this paper constructs a single-stage SEIR model and a multi-stage SEIR model of public opinion transmission in mobile network from the individual perspective,and further determines the threshold of public opinion transmission.
