Abstract

Aiming at the coexistence of positive and negative information in the process of network public opinion dissemination, this paper introduced positive information clarifier C on the basis of the SIR model to construct an SCIR model for the simultaneous dissemination of positive and negative information. Considering the homepage effect and the heterogeneity of netizens, this paper used multi-agent simulation technology to simulate the spread of public opinion. The simulation results show that the SCIR model is more consistent with the dissemination of public opinion in the real network than the SIR model. The higher the credibility of the statements made by third-party organizations on the homepage, the more conducive to the control of public opinion, but there are thresholds. The homepage effect has both positive and negative effects on the results of online public opinion. Both the heterogeneity of netizens and the dissemination rate of positive and negative information have a significant impact on the outcome of the competition between positive and negative information.
