基于信息风险感知的社交网络舆情传播模型研究
A Public Opinion Dissemination Model on Social Networks Based on Perception of Risks
摘要
Abstract
In view of practical behavior of social network users, this paper analyzes the modes of public opinion in social network, con-structs a dissemination model of public opinion in social network and built a mathematical model for spread probability based on perceived information risk. The results of simulation show that:informed probability has effect on the diffusion scale and the relaxation time;mean-while, perceived information risk has a greater impact on the relaxation time. The cause is that the spread probability can determine the number of spreaders directly, and the spread probability is determined by perceived information risk.关键词
