AI Technical Summary
Existing technologies for controlling the spread of misinformation in cross-media environments suffer from limitations in model building, inefficient control strategies, and a lack of optimization methods, resulting in poor prevention and control effects or excessively high costs. They also fail to accurately characterize the dynamics of misinformation spread and cannot balance control costs with the loss of misinformation.
A cross-media misinformation propagation model (XYD-SIFMR) is constructed. By defining node state variables and state transition rules, a differential dynamic system is established. The cost objective function is constructed using the three-dimensional control strategy strength parameters as optimization variables. The optimal control solution is solved, and purification, treatment, and blocking strategies are implemented to control the propagation of misinformation.
It enables precise control of the spread of misinformation in cross-media environments, significantly reduces the scope of the impact of misinformation, balances control costs and information loss, and is applicable to scenarios such as social platforms, news websites and friend groups, and has good engineering application value.
