Abstract In order to explore the propagation mechanism of rumors in online social networks, this paper takes into account the fact that rumor-promoters and rumor-debunkers coexist and establishes a new SPIDR (Susceptible-Promoted-Infective-Debunked-Recovered) rumor propagation model on the basis of SIR (Susceptible-Infective-Recovered) model, and then the stability of the model is analyzed. The simulation results show that the number of rumor-promoters and rumor-debunkers will affect the spread of rumors. Controlling the number of rumor-promoters will reduce the risk of rumor spreading. In addition, improving the probability of debunking rumors to ignorant people can effectively suppress the spread of rumors. The SPIDR rumor propagation model and simulation results will provide theoretical supports for relevant government departments or organizations to carry out rumor governance.
