论文摘要
焦点理论描述了共同的成员资格，社会地位，信念和地点如何促进社会关系的形成，而两模式的预测为将个人成员的两种模式数据转换为他们可能的社会关系的单模式网络提供了一种方法。在本文中，我探讨了相反的过程：社交关系如何促进组的形成，以及如何从一个模式网络中生成两模式网络。我提出了三种模型，这些模型借鉴了团队组成，俱乐部加入和组织招聘的理论，这些模型描述了这些团体如何从社交网络中的关系中出现。我表明，这些模型可用于生成具有经验两种模式社交网络中通常观察到的特征的两种模式网络，并且它们编码生成的单模网络的特征。我通过讨论这些模型的局限性以及有关群体形成的理论和方法的未来方向来总结。
Focus theory describes how shared memberships, social statuses, beliefs, and places can facilitate the formation of social ties, while two-mode projections provide a method for transforming two-mode data on individuals' memberships in groups into a one-mode network of their possible social ties. In this paper, I explore the opposite process: how social ties can facilitate the formation of groups, and how a two-mode network can be generated from a one-mode network. Drawing on theories of team formation, club joining, and organization recruitment, I propose three models that describe how such groups might emerge from the relationships in a social network. I show that these models can be used to generate two-mode networks that have characteristics commonly observed in empirical two-mode social networks, and that they encode features of the one-mode networks from which they were generated. I conclude by discussing these models' limitations, and future directions for theory and methods concerning group formation.
