Cross-network propagation model of public opinion information and its control in coupled double-layer online social networks

Purpose In modern society, considering the multi-channel of public opinion information (public opinion) propagation and its strong influence on social development, it is necessary to study its propagation law and discuss the intervention strategy in online social networks (OSN). Design/methodology/approach First, a conceptual model of double-layer OSN was constructed according to their structural characteristics. Then, a cross-network propagation model of public opinion in double-layer OSN was proposed and discussed its spreading characteristics through numerical simulations. Finally, the control strategy of public opinion, especially the timing and intensity of intervention were discussed. Findings The results show that the double-layer OSN promotes the propagation of public opinion, and the propagation of public opinion in double-layer OSN has the characteristics of that in two single-layer OSN. Compared with the intervention intensity, the regulator should give the priority to the timing of intervention and try to intervene in the early stage of public opinion propagation. Practical implications This study may help the regulators to respond to the propagation of public opinion in OSN more actively and reasonably. Originality/value This research has a deep comprehension of the cross-network propagation rules of public opinion and manages the propagation of public opinion.
