动态社交网络中的时间保真度

Temporal Fidelity in Dynamic Social Networks

Arkadiusz Stopczynski, Piotr Sapiezynski, Alex 'Sandy' Pentland, Sune Lehmann

摘要:

最近,以高分辨率记录大型社会系统中的详细社会互动已经成为可能。当我们研究这些数据集时,人类社会互动显示出从几分钟到几个月的多个时间尺度上出现的模式。在基本层面上,对网络动态的理解可以用于为测量社交网络的过程提供信息。当考虑动态过程时,测量的细节是特别重要的,其中分钟到分钟的细节是重要的,因为收集具有高时间分辨率的物理邻近相互作用是困难和昂贵的。在这里,我们考虑的是参与哥本哈根网络研究的大约500个人之间的邻近互动的动态网络。我们表明,为了准确地模拟网络中的传播过程,发生在几分钟的顺序的动态过程是必不可少的,必须包括在分析中。

英文摘要:

It has recently become possible to record detailed social interactions in large social systems with high resolution. As we study these datasets, human social interactions display patterns that emerge at multiple time scales, from minutes to months. On a fundamental level, understanding of the network dynamics can be used to inform the process of measuring social networks. The details of measurement are of particular importance when considering dynamic processes where minute-to-minute details are important, because collection of physical proximity interactions with high temporal resolution is difficult and expensive. Here, we consider the dynamic network of proximity-interactions between approximately 500 individuals participating in the Copenhagen Networks Study. We show that in order to accurately model spreading processes in the network, the dynamic processes that occur on the order of minutes are essential and must be included in the analysis.
