Propagation of Social Emotion in Cyber Space Based on Cognitive Social Psychology

This paper employs human cognitive process to analyze the cascade phenomena of subjective Web knowledge. First, the cognitive sentiment calculation is summarized in three stages. Second, attributes of users' background knowledge are mined. Clustering phenomena exist in users' background knowledge, which means that users are interested in certain kind of topics. Moreover, they tend to review external information about these topics. Third, how users' background knowledge impacts emotion decision making is analyzed. The impact is illustrated as the induction of objective and objective information. At last, the cascade phenomena of emotion propagation in cyber space are explained with users' selective emotion expression. Methods are proposed to interrupt cascade phenomena to reduce the negative impacts of cyber space to human beings. This paper mainly focuses on the psychological space and cyber space, which highlights the propagation mechanism of social emotion in cyber space.
