摘要
舆情交互存在于现实空间与虚拟空间,为具体研究两空间中舆情的演化,首先分析了舆情在不同空间中传播演化的特点及演化过程中相互间的联系.随后,结合改进的有界信任机制构建基于超网络的线上线下舆情演化模型,并针对该模型提出了包括模型初始化模块、信息传播与交互影响模块与双空间同步模块三部分的仿真系统框架.根据同步方向,提出"现实空间-虚拟空间"和"虚拟空间-现实空间"两种同步率,并通过对比仿真实验研究了同步率与空间速度比对舆情演化的影响.
The interaction of public opinion exists in both the real space and the virtual space.To specifically study the evolution process of public opinion in the two spaces,we first analyzed the characteristics of the evolution of public opinion in different spaces and the link between them in the process of evolution.Then,combined with the improved Hegselmann-Krause(HK)model,the online and offline public opinion evolution model based on the supernetwork was constructed.We also proposed a simulation system framework including initialization module,information propagation and interaction module and synchronization module.According to the direction of synchronization,two kinds of synchronization rate,real space-virtual space and virtual space-real space were proposed.Finally,through simulation experiments,the influence of synchronization ratio and space velocity radio on the evolution of public opinion was discussed.
