SIR model considering influence of network rumor propagation

The spread scope of online rumor is related to rumor influence, which in turn is related to the importance of rumor event, the vagueness of rumor evidence, and the cognitive ability of rumor contacts. This paper considers the reality that rumor influence is large in the initial stage of rumor transmission and gradually decreases with the passage of time, and takes rumor influence into account in the transmission probability of SIR model, so that the transmission probability becomes a dynamic function. The simulation results show that the SIR model considering the influence of rumor makes the peak value of rumor spreaders lower and reach the peak value later.
