摘要:

通信网络具有短路径的小世界特性,但其传播动力学过程是缓慢的。我们遵循通过通信网络的信息传播的时间演化,通过使用SI模型与接触序列的经验数据。我们引入空模型,其中序列以不同的方式随机洗牌,使我们能够区分不同阻碍效应的贡献。扩散的减缓主要是由体重拓扑相关性和个体的突发性活动模式引起的。

英文摘要:

Communication networks show the small-world property of short paths, but the spreading dynamics in them turns out slow. We follow the time evolution of information propagation through communication networks by using the SI model with empirical data on contact sequences. We introduce null models where the sequences are randomly shuffled in different ways, enabling us to distinguish between the contributions of different impeding effects. The slowing down of spreading is found to be caused mostly by weight-topology correlations and the bursty activity patterns of individuals.
