Abstract
Traditional media has always been the main medium of information dissemination. In order to solve the negative effects on information flooding, truth and falsehoods in social network communication, a trust model of netizens is proposed. The Deffuant model is analyzed and the trust network is constructed according to the interaction behavior between the netizens and the government and the characteristics and definitions of the trust relationship. Netizens trust model describes the trust degree between netizens and the government. Then the simulation is carried out under different degrees of trust through MATLAB. The influence of the trust degree on social network dissemination is observed by changing the step size. Based on the analysis of the simulation results, we can conclude that when the trust between the netizens and the government is large, it’s easier to reach a consensus. It plays a positive role in promoting dissemination.
