- Abstract:

The spread of disinformation on online social networks (OSNs) has become a critical challenge for cyberspace security governance. This paper presents DDC-UPRNI, a disinformation diffusion control method, by integrating user propagation risk with node influence analysis. First, comprehensively considering the diversity and complexity of the characteristic space of disinformation propagation, an embedded representation of the behavior, time and content dimensions of user propagation of disinformation is realized through the self-attention mechanism, and the automatic classification of different user propagation risk levels is achieved using the improved unsupervised clustering K-means++ algorithm. Second, an adaptive weighting strategy is designed to improve the discrete particle swarm optimization algorithm, and a method for selecting key nodes of disinformation propagation is proposed based on the discrete particle swarm optimization. This method determines several influential control driving nodes from the user node set with a specific propagation risk level to achieve accurate and highly efficient disinformation propagation control. Finally, experiments are performed on a real OSN platform, and the results demonstrate that the proposed DDC-UPRNI method has obvious advantages over other existing algorithms in some important indicators, including control effect and time complexity. This method provides a significant reference value for the current governance of disinformation in social cyberspace.
