【目的/意义】为了探究复杂网络中信息的传播机制以及不同网络中的信息推动力。【方法/过程】本文利用邻居节点特性与信息公信力确定传播规则,探究了小世界与无标度网络中的信息传播,并研究了节点对爆发规模的影响差异。【结果/结论】结果发现:无标度网络中信息传播的驱动力倾向于从众效应,而小世界网络则主要源于信息本身;不同k-shell值的节点对无标度网络爆发规模的影响比小世界网络显著;不同度值的节点对二者的爆发规模影响均显著。
Purpose / Significance To explore the mechanism of information dissemination in complex networks and the driving force of information in different networks. [Method / Procedure] This paper uses the characteristics of neighbor nodes and information credibility to determine the propagation rules, explores the information propagation in small-world and scale-free networks, and investigates the differences in the impact of nodes on the outbreak scale. [Results / Conclusion] The results show that the driving force of information spreading in scale-free networks tends to follow the effect of public, while the small-world network mainly comes from the information itself. The impact of nodes with different k-shell values on scale-free network explosion Which is more significant than the small-world network. The nodes of different degrees have significant impact on the scale of the two outbreaks.
