Research on public opinion reversal phenomenon of network mass events modelling and simulation

摘要

At the present, network mass incidents occur frequently, and the network public opinion of the non-directional reversal causes great concern. Based on the JA model, this paper focuses on the evolution process of the dynamic attitude reversal of the network group, taking the important information of the outside world as a variable, exploring the influence of the important information release on the whole public opinion, and using the multi-agent Monte Carlo method for experimental simulation. This paper takes the Guizhou bus crash incident as an example to make an empirical analysis.
