摘要
[目的/意义]信息疫情传播的实质是真假信息竞争性传播的过程,厘清信息疫情中真假信息竞争性传播机理,对信息疫情管控策略的制定具有重要意义。[方法/过程]基于流行病模型结合用户创作行为特性构建了FT-SIR模型,求解所构建动力学模型的平衡点并进行稳定性分析,利用NetLogo模拟真假信息竞争性传播过程,同时针对微博的典型案例数据验证模型的有效性。[结果/结论]实验表明,在用户创作行为的作用下,单一信息在传播过程中会发生变异并催生真假信息的竞争性传播;“信息茧房”效应及意见领袖的存在使得用户具有不同的角色特质,进而对真假信息的竞争性传播产生显著影响。为政府采取措施降低信息疫情的危害提供了具体的管控策略与建议。
[Purpose/Significance]The essence of infodemic is the process of competitive propagation between true and false information.Clarifying the mechanism of competitive propagation between true and false information in infodemic is of great significance to the formulation of infodemic intervention strategies.[Method/Process]FT-SIR model was constructed based on epidemic model and user creative behavior characteristics.It solved the equilibrium point of the dynamical model and conducted stability analysis.Using NetLogo to simulate the competitive propagation process between true and false information,and verify the effectiveness of the model against the typical case data of Weibo.[Result/Conclusion]The experiment shows that under the influence of user s creative behavior,information will change in the process of propagation and promote the competitive propagation between true and false information.The“information cocoons”effect and the existence of opinion leader enable users to have different role characteristics,thus having significant effects on the competitive propagation between true and false information.It provides specific intervention strategies and suggestions for the government to take measures to reduce the harm of infodemic.
