Identifying Influential Rumor Spreader in Social Network
Discrete Dynamics in Nature and Society, 2019 It is of great significance to identify influential rumor spreaders for preventing and controlling the rumor propagation. In this paper, on four real social networks, based on the classical rumor model and combining one-to-many modes of propagation, we ...

A Fractional-Order SIR-C Cyber Rumor Propagation Prediction Model with a Clarification Mechanism
Axioms, 2022 As communication continues to develop, the high freedom and low cost of the communication network environment also make rumors spread more rapidly. If rumors are not clarified and controlled in time, it is very easy to trigger mass panic and undermine ...
