A rumor propagation model in the context of recommendation

Abstract： With the change of the way of information transmission, rumor information transmission based on recommendation platform has become an important way of rumor transmission. The construction of rumor transmission model based on recommendation mechanism plays a positive role in the governance of Internet rumor. Considering the segmentation effect of recommendation mechanism on users, the concept of propagation domain was proposed in the process of rumor propagation, the interaction mode between users and information in the propagation domain was defined, and a rumor propagation model based on rumor information heat and platform user density was proposed.The factors that influence the spread of rumor information were simulated and analyzed. It was found that under the recommendation mechanism, people′s acceptance rate of information is mainly affected by the information itself; on the recommendation platform, increasing the threshold of rumor information dissemination is beneficial to prevent the spread of rumors; the greater the acceptance rate of rumors, the higher the time requirement for the rumors refuting information.
