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 ...

Dynamic Analysis of a Fractional-Order SINPR Rumor Propagation Model with Emotional Mechanisms

Fractal and Fractional
The inherent randomness and concealment of rumors in social networks exacerbate their spread, leading to significant societal instability. To explore the mechanisms of rumor propagation for more effective control and mitigation of harm, we propose a ...

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 ...
