Abstract EN
In recent years, increasing attention has been paid to how to effectively manage rumor propagation.
Based on previous studies of rumor propagation and some strategies used by the authorities to refute rumors and manage rumor propagation, we develop a new rumor-propagation model with consideration of refutation mechanism.
In this paper, we describe the dynamic process of rumor propagation by accounting for the refutation mechanism in homogeneous social networks.
And then, we derive mean-field equations for rumor-propagation process.
We then analyze the stability of the model with respect to changes in parameter values.
Our results show that there exists a critical threshold λc that is inversely proportional to the average degree of the social networks and is positively correlated with the strength of the refutation mechanism.
If the spreading rate is bigger than the critical threshold λc, rumors can be spread.
Our numerical simulations in homogeneous networks demonstrate that increasing the ignorant’s refutation rate β can reduce the peak value of spreaders density, which is better than increasing the spreader’s refutation rate η.
Therefore, based on the seriousness of the rumor propagation and the rumor-propagation rate, the authorities can choose effective strategies that increase the refutation rate so that they can reduce the maximum influence of the rumor.
