Research On Network Public Opinion Model Based On Opinion Dymanics

This paper establishes a model of network public opinion evolution based on opinion dynamics. This model improves Hegselmann-Krause model of opinion dynamics. It regards government control, social distance in social software and personal mentality as three influencing factors. Considering the influence of factors on propagation probability, it calculates opinion propagation probability and gives a description of the process of opinion dissemination in different situations. Based on the model, it carries out the simulation experiments of network public opinion communication. The simulation results show that the government can take measures to guide the public opinion when dealing with the network public opinion of sudden security events, so as to provide a theoretical basis for the network public opinion guidance.
