Research on Information Diffusion in Double Layer Networks Under Spatiotemporal Separation
[Purpose/significance]Clarifying the influence of spatiotemporal partition on information diffusion is of some signifi-cance in reducing information redundancy and establishing good social relations.[Method/process]Considering the influence of offline spatiotemporal separation on information diffusion,based on the infectious disease model,this paper used office offline uniform network,random walk network and online network to couple to construct a two-layer information diffusion network model,and analyzed the infor-mation diffusion behavior on these two types of two-layer networks through numerical simulation.[Result/conclusion]Compared with the single-layer network,the information diffusion in the two-layer network is wider in scope,faster in speed and shorter in duration;when the partition time is increased sequentially,the scope and speed of the information diffusion will gradually decrease and the dura-tion will be prolonged accordingly;when the spatial and temporal partitions are 6,the information diffusion of the two-layer network is less efficient and less extensive than that of the single-layer network.
