Abstract
In this paper, we hypothesize that the number of followings users have
on social networks, has an influence on the impact level of the received
rumor/anti-rumor messages by those users. We show that influence as a
decreasing exponential coefficient on the probabilities by which users'
might get affected from the received messages. Then we put forward
another hypothesis that suggests that rumor/anti-rumor posts gradually
lose their impact power by passage of time. To assign this time-related
feature to the posts, we consider a memory for each agent of the
network. Finally, we derive stochastic equations of the new model which
incorporate both of the new hypotheses and then evaluate it based on
real datasets of rumor spreading on Twitter. The evaluation results
support the new hypotheses and show that the novel model is able to
better represent rumor spreading on online social networks. (c) 2019
