Model Evaluation of Opinion Diffusion Networks Based on the Mechanism-Inferring Method

Current research on model evaluation of opinion diffusion networks has some drawbacks. This paper investigates an empirically-built opinion diffusion network based on the mechanism-inferring method. On the basis of the evaluation of predicting performance of four typical network models, some improvement suggestions have been given by the fitting analysis of network micro-structure. The effectiveness of the evaluation result has been verified by the investigation of accuracy and robustness. This research objectively discloses the evolution mechanism of opinion diffusion networks, which is significant for the next study about model constitutions and dynamical processes of opinion diffusion on such networks.
