社会关系在信息传播中的动力强度

The dynamical strength of social ties in information spreading

Giovanna Miritello, Esteban Moro, Rubén Lara

摘要:

我们研究人类交流的时间模式及其对社交网络中信息传播的影响。对一个国家2000万人的手机通话的分析表明,人类的交流是突发性的,并且发生在群体对话中。这些特征在信息到达方面具有相反的效果:当突发阻碍大规模传播时,对话有利于局部快速级联。为了解释这些现象,我们定义了社会联系的动态强度,这个量包含了人类交流的拓扑和时间模式。

英文摘要:

We investigate the temporal patterns of human communication and its influence on the spreading of information in social networks. The analysis of mobile phone calls of 20 million people in one country shows that human communication is bursty and happens in group conversations. These features have opposite effects in information reach: while bursts hinder propagation at large scales, conversations favor local rapid cascades. To explain these phenomena we define the dynamical strength of social ties, a quantity that encompasses both the topological and temporal patterns of human communication.
