耦合人类流动和社会联系

Coupling Human Mobility and Social Ties

Jameson L. Toole, Carlos Herrera-Yague, Christian M. Schneider, Marta C. Gonzalez

摘要:

使用从通信技术中被动收集的大量数据的研究揭示了社交网络的许多普遍存在的方面,帮助我们理解和建模社交媒体,信息传播和组织动态。最近,这些数据被贴上了地理信息的标签,使人们能够研究人类流动模式和城市科学。我们结合这两种追求,并发现社会联系中可重复的流动模式。首先,我们介绍了移动性的相似性和可预测性的措施,并在三个大的城市地区的用户群体来衡量它们。我们发现,个体的拜访模式与社会联系比陌生人更相似,更可预测,这些措施与关系强度呈正相关。移动相似性的小时变化的无监督聚类确定了三类社会关系,并表明地理位置是将社会关系置于背景中的重要特征。我们发现,一个用户的自我网络的组成,他们保持的接触类型与移动行为相关。最后,我们扩展了一个流行的流动性模型,包括基于社会联系的运动选择,并比较它的能力,再现经验测量与两个额外的模型的流动性。

英文摘要:

Studies using massive, passively data collected from communication technologies have revealed many ubiquitous aspects of social networks, helping us understand and model social media, information diffusion, and organizational dynamics. More recently, these data have come tagged with geographic information, enabling studies of human mobility patterns and the science of cities. We combine these two pursuits and uncover reproducible mobility patterns amongst social contacts. First, we introduce measures of mobility similarity and predictability and measure them for populations of users in three large urban areas. We find individuals' visitations patterns are far more similar to and predictable by social contacts than strangers and that these measures are positively correlated with tie strength. Unsupervised clustering of hourly variations in mobility similarity identifies three categories of social ties and suggests geography is an important feature to contextualize social relationships. We find that the composition of a user's ego network in terms of the type of contacts they keep is correlated with mobility behavior. Finally, we extend a popular mobility model to include movement choices based on social contacts and compare it's ability to reproduce empirical measurements with two additional models of mobility.
