Modelling public opinion polarisation process considering the influence of initial viewpoint and interaction mode

As an important media, there is often a polarisation of the internet group triggered by hot social topics, and the emotions of netizens will react on the society. These effects are sometimes positive or negative, so it is urgent to conduct in-depth research and study. Behind the polarisation phenomenon is the change of people's attitude towards events, such as convergence, alienation and neutrality. Considering the priority possession theory, this paper focuses on the influence of initial attitude on the evolutionary process. On the basis of J-A model (proposed by Jager and Amblard), the influence function of the initial viewpoint is added, and the computer simulation experiment is carried out and the concrete example is taken for empirical analysis.
