让你的朋友更亲密,让你的Facebook朋友更亲密:分析离线和在线社交关系的多重网络方法

Keep Your Friends Close and Your Facebook Friends Closer: A Multiplex Network Approach to the Analysis of Offline and Online Social Ties

Desislava Hristova, Mirco Musolesi, Cecilia Mascolo

摘要:

社交媒体允许人们在网上进行前所未有的互动。然而,人类社会行为的一个基本方面是人们倾向于将自己与志同道合的人联系起来,形成在线和离线的同质社交圈。在这项工作中,我们应用了一个新的模型,使我们能够区分不同强度的社会关系,并观察在74名大学生的在线和离线社交网络中,关于政治,音乐,健康,住宅部门和大学一年的同质性证据。我们提出了一个多路复用网络的方法,社会关系的强度,在这里应用到移动通信数据-电话,短信,并共同定位,使我们能够通过考虑学生之间利用的通信渠道的数量来确定维度的关系。我们发现,强的社会关系的特点是最大限度地利用沟通渠道,而弱的关系,最小的使用。我们能够识别75%的亲密友谊,90%的弱关系,以及90%的Facebook友谊。然后,我们表明,较强的关系表现出更大的配置文件的相似性比较弱的。除了在政治和健康方面的社会圈子高度同质性,我们观察到音乐,住宅部门和大学一年的强烈同质性。尽管Facebook友谊高度依赖于居住地和年份,但学生的在线社交圈而不是线下社交圈中可以发现不太同质的内容,尤其是在政治和音乐方面。

英文摘要:

Social media allow for an unprecedented amount of interaction between people online. A fundamental aspect of human social behavior, however, is the tendency of people to associate themselves with like-minded individuals, forming homogeneous social circles both online and offline. In this work, we apply a new model that allows us to distinguish between social ties of varying strength, and to observe evidence of homophily with regards to politics, music, health, residential sector & year in college, within the online and offline social network of 74 college students. We present a multiplex network approach to social tie strength, here applied to mobile communication data - calls, text messages, and co-location, allowing us to dimensionally identify relationships by considering the number of communication channels utilized between students. We find that strong social ties are characterized by maximal use of communication channels, while weak ties by minimal use. We are able to identify 75% of close friendships, 90% of weaker ties, and 90% of Facebook friendships as compared to reported ground truth. We then show that stronger ties exhibit greater profile similarity than weaker ones. Apart from high homogeneity in social circles with respect to political and health aspects, we observe strong homophily driven by music, residential sector and year in college. Despite Facebook friendship being highly dependent on residence and year, exposure to less homogeneous content can be found in the online rather than the offline social circles of students, most notably in political and music aspects.
