| 中文简介: |  个人的个人网络（即他们的社交联系）是社会学研究的基本对象。对个人网络的研究集中在其规模（联系人数量）及其组成（按亲属和同事等类别）。在此，我们根据个人将注意力集中在各个联系人之间的方式，提出了一种用于分析个人网络的新方法。这使我们能够将那些将大部分互动集中在少数密友上的人与分散注意力的人进行对比。使用来自Facebook的数据，我们发现注意力的平衡是个人随时间推移相对稳定的属性，并且它在不同人群和不同交互方式之间都显示出有趣的变化。特别是，基于交流的活动比单纯基于观察的活动涉及更多的关注焦点，并且这两种类型的方式在组内和组间的交互模式上也表现出不同形式的变化。最后，我们将个人对他们最频繁接触的注意力的关注程度与这些接触者的身份变化率进行了对比，从而为这一组用户提供了流失率的测量方法。 |
| 课程简介: | An individual’s personal network — their set of social contacts—is a basic object of study in sociology. Studies of personal networks have focused on their size (the number of contacts) and their composition (in terms of categories such as kin and co-workers). Here we propose a new measure for the analysis of personal networks, based on the way in which an individual divides his or her attention across contacts. This allows us to contrast people who focus a large fraction of their interactions on a small set of close friends with people who disperse their attention more widely. Using data from Facebook, we find that this balance of attention is a relatively stable property of an individual over time, and that it displays interesting variation across both different groups of people and different modes of interaction. In particular, activities based on communication involve a much higher focus of attention than activities based simply on observation, and these two types of modalities also exhibit different forms of variation in interaction patterns both within and across groups. Finally, we contrast the amount of attention paid by individuals to their most frequent contacts with the rate of change in the identities of these contacts, providing a measure of churn for this set. |
