Romantic Partnerships and the Dispersion of Social Ties: A Network Analysis of Relationship Status on Facebook 恋爱关系和社会关系的分散性:Facebook 恋爱婚姻关系的网络研究

Abstract 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. 论文摘要 在线社交网络系统的分析中的关键任务是在个体单独的网络关系的范围之内来辨别那些重要的人(那些由强烈的社会关系纽带联系在一起的人群)。在此我们通过调查包含配偶或恋爱对象在内的一个具有紧密关系纽带的特定人群类型来探讨这个问题。我们围绕着一个基本问题来组织我们的分析:给定单独个体所有朋友间的联系,你能仅靠网络结构来辨认出他或她的恋人吗?我们发现通过使用来自Facebook用户组成的大样本数据,这个实验目标可以被非常准确的完成,但这样做需要我们对命名为“分散性”(即两个人的共同好友间不是通过他们自己保持紧密关系的程度为多少)的关系强度的新测定方法进行改善。该研究结果为识别那些在网络应用中具有结构性显著特征的人群类型提供了方法且提供了一个对关系强度现存理论的潜在扩展。
