Personalized Crowd Emotional Contagion Coupling the Virtual and Physical Cyberspace

Crowd emotional contagion is affected by physical cyberspace and virtual cyberspace at the same time. In addition, the individual personality also plays an important role in crowd emotional contagion. However, few existing works have investigated the two factors jointly. To solve this problem, we propose a personalized virtual and physical cyberspace-based emotional contagion model (PVP-ECM) to simulate the process of crowd emotional contagion. First, we construct an individual emotion model and propose the personalized emotional contagion rules to consider the influences of the individual personality on crowd emotional contagion coupling the virtual and physical cyberspaces. Second, we use mean field theory to derive an evolution process and obtain mean field equations for the PVP-ECM. Then, we solve the PVP-ECM numerically using the finite difference method. Third, we construct a personalized BA scale-free network for the PVP-ECM simulation to further verify the stability of the model. Finally, we perform the PVP-ECM simulation and implement a simulation system to visualize the results of our theoretical analysis. The experimental results show that our approach can simulate the process of crowd emotional contagion more realistically. The proposed method can provide guidance for coping with the personalized crowd emotional contagion of public emergencies.
