Abstract Fission mode of information transmission in the micro-blog network presents a challenge to the existing public opinion propagation model. In order to depict the mechanism of the public opinion transmission in the complex network formed by users' attention relationship in micro-blog, the paper proposes an SIRS model of public opinion propagation based on the directed BA n etwork.The model considers the propagation characteristics of micro-blog, and derivatives of public opinion topics and other factors comprehensively.The simulation results can verify the validity of the model.
