In recent years,people's access to social network information and delivery more and more dependent on the network with the rapid development of social networks.Either the largest foreign social networking sites Facebook,MySpace,etc,or the most popular microblogging,WeChat and so on.Users can repost and share information through this mainstream network media platform.Social network has now become a huge social influence and public appeal of the most popular important communication tool for its unique dissemination of the advantages and strong influence.Social network is indeed convenience to human,but it also has produced some social problems.Some false information spread through the network more rampant,which not only seriously threaten social stability but slao affect the normal development of human market economy.Therefore,the study of rumors in the social network of the spread of the law is a hot spot.This paper analyzes the characteristics of information dissemination in social networks and introduces the common information dissemination model and network model.The traditional dynamic model of infectious diseases is one of the important ways to study rumors.However,most of them are the effects of individual factors on the spread of rumors,but the transmission of actual rumors is influenced by many factors.This paper corrects the traditional virus SIR information dissemination model by introducing a latent state node,and introduces two functions in the process of transitioning the rumors to the latent state node.One is the function of the interest attenuation mechanism,the othrer is a function of the social strengthening mechanism.And finally constructed an ISPR rumor information dissemination model.Then the dynamic evolution equations are deduced from the constructed ISPR model,and the simulation is carried out using Matlab and Python simulation software to analyze the influence of these two mechanisms on the spread of rumors.The relationship between rumors and interest decay is negative feedback,and the positive relationship is expressed with the social strengthening mechanism,and it is found that the spread of rumors is not monotonically increasing,but the trend of increasing first and then decreasing.
