Based on the analysis of social network structure,this paper introduces the hot transmission node into network,and proposes an information transmission model based on the improved SIR model,which is simulated with the data-based Tumblr social network.The simulation results show that with the decrease of immune probability and the increase of contact between the Internet marketers or ordinary information disseminators and those easily infected,the information transmission scope and velocity in the network will be enhanced to some degree.Without artificial control,the information will be disseminated to a vast majority of the users in a specific social network.The improved information transmission model can reveal the inherent law of information transmission in social network more accurately.
