人们如何在社交网站上交友-微观视角

How people make friends in social networking sites - A microscopic perspective

Haibo Hu, Xiaofan Wang

摘要:

我们研究的详细增长的社交网站与完整的时间信息,通过检查每个友谊关系,可以共同导致网络的宏观属性的创建过程。我们首先研究了用户的交互行为,发现链接请求被快速响应,交互间隔的分布呈指数形式衰减。邀请者/接受者的程度与往返时间呈轻微负相关。此外,在线社区的时间特征表明,用户行为(如发送或接受链接请求)的时间间隔分布遵循普适指数的幂律,峰值出现在整数天的时间间隔内。我们最后研究了社交网站的优先选择和链接现象,发现对于前者,优先发送和接收的线性偏好成立,对于后者,优先接受,创建和连接的线性偏好也成立。基于线性优先连接,提出了一个可解析的网络模型,该模型能够再现网络的度分布。本文提出的研究框架可以提供一个潜在的洞察用户的微观动机如何导致在线社交网络的全球结构。

英文摘要:

We study the detailed growth of a social networking site with full temporal information by examining the creation process of each friendship relation that can collectively lead to the macroscopic properties of the network. We first study the reciprocal behavior of users, and find that link requests are quickly responded to and that the distribution of reciprocation intervals decays in an exponential form. The degrees of inviters/accepters are slightly negatively correlative with reciprocation time. In addition, the temporal feature of the online community shows that the distributions of intervals of user behaviors, such as sending or accepting link requests, follow a power law with a universal exponent, and peaks emerge for intervals of an integral day. We finally study the preferential selection and linking phenomena of the social networking site and find that, for the former, a linear preference holds for preferential sending and reception, and for the latter, a linear preference also holds for preferential acceptance, creation, and attachment. Based on the linearly preferential linking, we put forward an analyzable network model which can reproduce the degree distribution of the network. The research framework presented in the paper could provide a potential insight into how the micro-motives of users lead to the global structure of online social networks.
