基于多尺度时效模体度的虚假信息传播机制

False Information Dissemination Mechanism Based on Multi-Scale Temporal Motif

  • 摘要: 将时效网络引入虚假信息传播研究中,提出一种通过时效模体度刻画传播网络的方法来探究虚假信息的传播机制。该方法将传播网络的结构特性和信息的时间属性相融合,使用多个真实数据集检验了该方法在虚假信息检测中的普适性。数据结果表明,真假信息在不同的时间尺度下时效模体度的变化规律不同,在大时间尺度上虚假信息比真实信息的传播速度更快且传播深度更深,利用基于时效模体度的方法可以更准确地检测出虚假信息。该研究揭示了虚假信息的多时间尺度传播机制,可用于预防虚假信息的传播。

     

    Abstract: This paper tries to introduce temporal network into the study of disinformation propagation, and proposes a method to explore the propagation mechanism of disinformation by carving the propagation network through Temporal Motif, which integrates the structural characteristics of the propagation network and the temporal properties of information, and also uses several real data sets to test the generalizability of the method in disinformation detection. Based on the results of empirical data, it is shown that the change patterns of true and false information are different at different time scales Temporal Motif, and false information spreads faster and deeper than true information at large time scales, and false information can be detected more accurately using the method based on the temporal modal degree. This study reveals the multi-timescale propagation mechanism of false information, which can be used to prevent the propagation of false information.
