Crowd Behavior Evolution With Emotional Contagion in Political Rallies

In this paper, we present a novel crowd behavior evolution method with emotional contagion in political rallies. We first analyze the most representative political rally scenes in detail and model them into two kinds of abstract scenario. Furthermore, the “extroversion” and “empathy” factors from the OCEAN model are chosen to describe the most important individual personalities in such scenarios. Based on this, an improved emotional contagion model is proposed by combining the Susceptible-Infected-Recovered model and individual personality under different political viewpoints. Finally, the crowd in a political rally is driven to move according to the new potential moving direction generated by emotional contagion and the original direction of the individual together. The experiments show that our method can intuitively demonstrate the emotional changes of those individuals with different political perspectives and reasonably simulate the crowd movement under the political rally scenes.
