摘要 考虑到虚假信息要先于真实信息扩散且二者存在于同一个社会网络中的现象,研究了真假信息竞争扩散模型,分析比较了各种概率、真实信息初始扩散时间和扩散节点数量的影响。结果发现,采取措施降低节点扩散虚假信息的可能性可以减少虚假信息扩散范围,此外,仅当真实信息延迟扩散时间较短时,可通过增加节点扩散真实信息的可能性、增加扩散真实信息节点的数量或选择度较大的节点来扩散真实信息的方式来减少虚假信息扩散范围,并增加了真实信息覆盖面。

Abstract:Considering the phenomenon that false information is diffused before real information in social networks, an information competition diffusion model is studied and the effects of different probabilities, the initial diffusion time of real information and the number of real information spreader nodes are analyzed and compared. It is found that reduing the probability of unknown nodes to diffuse false information can reduce the diffusion scope of false information. In addition, only when the delay diffusion time of real information is short, can the diffusion scope of false information be reduced and the coverage of real information be increased by increasing the probability of nodes to diffuse real information, increasing the initial number of real information spreader nodes and selecting nodes with greater degree to diffuse real information.
