Improved SIR Advertising Spreading Model and Its Effectiveness in Social Network

The traditional SIR model cannot fully reflect the regularity of information propagation in social networks. In this paper, the advertising spreading model which is applied to social networks is established, and the corresponding dynamic evolution equations are given. Meanwhile, due to that there is no unified evaluation criteria for the validity of spreading models currently, the application of AEI, the advertising effectiveness index to evaluate and analyze the effectiveness of spreading models is put forward in this paper. The experiment results demonstrate that the model proposed in this paper can correctly reflect the trend of advertising spreading in social network, and accurately describe the spreading process, and the validity of the model is also verified in this paper.
