分析在线社交网络系统的一项关键任务是在一个人的网络邻居中识别重要人物——那些与强大的社会关系联系在一起的人。在这里，我们调查了一个特殊类别的强关系，包括配偶或恋人。我们围绕一个基本问题进行分析：给定一个人的朋友之间的所有联系，你能仅仅从网络结构中识别出他或她的恋人吗？通过使用来自大量Facebook用户样本的数据，我们发现这项任务可以以很高的准确率完成，但这样做需要开发一种新的联系强度衡量标准，我们称之为“分散度”——两个人的共同朋友本身没有很好联系的程度。研究结果提供了识别在线应用中结构重要人物类型的方法，并提出了现有联系强度理论的潜在扩展。
A crucial task in the analysis of on-line social-networking systems is to identify important people --- those linked by strong social ties --- within an individual's network neighborhood. Here we investigate this question for a particular category of strong ties, those involving spouses or romantic partners. We organize our analysis around a basic question: given all the connections among a person's friends, can you recognize his or her romantic partner from the network structure alone? Using data from a large sample of Facebook users, we find that this task can be accomplished with high accuracy, but doing so requires the development of a new measure of tie strength that we term `dispersion' --- the extent to which two people's mutual friends are not themselves well-connected. The results offer methods for identifying types of structurally significant people in on-line applications, and suggest a potential expansion of existing theories of tie strength.
