网络和群体的对偶性：从单模式网络生成双模式网络的模型
The duality of networks and groups: Models to generate two-mode networks from one-mode networks
摘要：
焦点理论描述了共享的成员身份、社会地位、信仰和地点如何促进社会关系的形成，而双模式预测提供了一种方法，将个体在群体中的成员身份的双模式数据转换为他们可能的社会关系的单模式网络。在本文中，我将探讨相反的过程：社会关系如何促进群体的形成，以及双模式网络如何从单模式网络生成。借鉴团队形成，俱乐部加入和组织招聘的理论，我提出了三个模型来描述这样的群体可能会出现在一个社会网络中的关系。我表明，这些模型可用于生成具有经验双模式社交网络中常见特征的双模式网络，并且它们对生成它们的单模式网络的特征进行编码。最后，我讨论了这些模型的局限性，以及未来的理论和方法的发展方向有关群体的形成。
英文摘要：
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.
