摘要：As the landscape of social networks evolves, the dissemination of public opinion through online channels has become increasingly dominant. Consequently, researchers have turned their attention to the impact of emotional factors introduced by communicators when conveying public opinion. This paper proposes a novel SEInIeR public opinion communication prediction model, incorporating an extreme emotion mechanism, which acknowledges the inuential nature of speech under heightened emotional states. By integrating the traditional infectious disease SEIR model with fractional order differentiation, our model not only ensures the existence and stability of the disease-free equilibrium point E0 but also allows for more accurate prediction. Finally, the model has been validated and analyzed through simulation experiments and numerical simulations. Furthermore, example data were collected for analysis and tting. The experimental results provide substantial evidence for the accuracy of our theoretical analyses and the plausibility of the proposed model.
