Rectifying the Misinformation in Social Network

Abstract

This paper proposes a rumor rectification model considering the context when rumor in the social network has propagated for a period of time such that it is too late to block the rumor. We give an explanation that existing models on rumor blocking are not appropriate in this case. TIM+ is an efficient approximation algorithm in influence maximization problem, however it handles the case when there is only one influence cascade in the network. We modify it to suit the two cascades case in our problem and find obvious effect comparing with the random solution.
