Analysis of the Process of Public Opinion Dissemination Based on the SCT Model and Model Improvement —Take the topic of “Small Town Exam-oriented Students” on Weibo as an example

The SCT model, which was created based on the WD model and describes the diffusion of public opinion, is unable to fully capture the evolution of public opinion. We examined the development and affecting aspects of “Small Town Exam-oriented Students” using the preprocessing of crawler data. Based on this fundamental concept, we suggested an enhanced SCT model. Initially, using the interaction amplitude control parameters, we described the impact of official media on public opinion. The value of the parameters determining how attractive a topic is was then the subject of a classified conversation. The experiment shown that, when compared to the conventional SCT model, our improved SCT model has a faster rate of convergence with no differences in the evolving results. The final evolving outcome typically agrees with the microblog content LDA model analysis result.
