基于观点认同的群体情绪模型

为了能够有效地模拟群体环境中群体情绪的演化过程, 以情绪感染为理论基础, 提出一种新的基于观点认同的群体情绪模型。该模型引入个体观点值、情绪触发阈值来实现观点交互与认同对群体情绪演化所产生的影响作用。观点交互采用有界信任Deffuant模型来实现。通过模拟发现, 观点交互不仅加速了群体情绪融合过程, 而且在多观点群体环境中对群体情绪融合态势也具有决定性的作用。实验模拟结果表明, 本模型不仅能够体现情绪感染过程中个体的无意识、自动感染过程, 而且也能够体现个体对传染对象的选择性过程, 弥补了情绪感染过程中个体无认知的缺陷。

Emotion model of crowd based on opinion identity

To make the simulation of the emotional evolution in crowd situation more realistic, this paper provided a new method of building the emotion model based on opinion identity. Individual opinion value and emotional trigger threshold, which were introduced in the model, were to reflect the effect made by opinion interaction on emotional evolution of crowd. Opinion interaction was implemented using the bounded confidence Deffuant model. Through the simulation, it can be concluded that opinion interaction not only accelerates the emotion convergence process but has the determining influence on the emotional situation of crowd with many opinions as well. In the process of emotional contagion, the model reflects the unconscious and automated process of individual, and embodies the selected process for infectious object. Especially, the individual opinion value remedies the no cognitive flaw of emotional contagion process.
