Modeling and Simulation of Network Public Opinion Communication Model for Public Opinion Field
In order to analysis the interaction mechanism between the official public opinion field and the folk public opinion field and its impact on the spatio-temporal transmission of Internet public opinion,and guide the prac-tice of information security governance based on the research conclusions.According to the interaction of the two pub-lic opinion fields and the characteristics of public opinion dissemination,an Internet public opinion dissemination model based on two-layer network is proposed and applied to study the impact of the interaction of two public opinion fields on thedissemination of Internet public opinion.First,the spreading threshold R0 of the model is solved in the pa-per,and then the equilibrium of public opinion propagation is analyzed based on R0.Secondly,the stability of the model at the equilibrium is analyzed according to the theory of Routh-hurwitz and Lyapunov.Finally,the propagation of Internet public opinion under different interactive scenarios of the two public opinion fields is simulated and ana-lyzed.The experimental results shows that the model is consistent with the real system and can more realistically sim-ulate the spatio-temporal spread of public opinion in the real cyberspace,which provides ideas for the integration and development of the two public opinion fields and the research on the guidance of Internet public opinion.
