SCIR Information Propagation Model Based on Influencing Factors of Forwarding Behavior
摘要
The research on the construction of information propagation model and the law of information transmission on the online social network is of great significance to restrain the spread of malicious information and strengthen the supervision of public opinion on the internet.Based on the analysis of hotspot events,a kind of new node named carrier node is added on the basis of the traditional Susceptible Infected Removed(SIR) model,and a new model named Susceptible Contacted Infected Removed(SCIR) model is established to describe the information diffusion better in online social network.As the analysis of the relationship between user interaction and forwarding behavior,the five characteristics of forwarding behavior are analyzed and described.By the theoretical analysis of the evolution equation of the epidemic dynamics,the difference between the SIR model and the SCIR model is given.Experimental results show that compared with the SIR model,the SCIR model has better stability and information coverage.
