我们认为，社交网络可以被建模为过程的结果，发生在重叠的局部区域的网络，称为当地的社会邻里。每个邻域被认为是一个可能的相互作用的网站，并对应于一个子集的可能的网络关系。在本文中，我们讨论了这些社区的形式的假设，我们提出了两个新的和理论上合理的方法，可以构建基于邻居的网络模型。在第一，我们引入的概念，设置结构，一个直接假设（或观察）的一组可能的邻域形式的外源性约束。在第二个，我们提出了高阶社区，产生的，在一定程度上，由互动网络过程本身的结果。这两种方法的模型构建的应用，并被认为是一个一般的概念框架内的社交网络的位置的发展。我们展示了如何假设的街区可以投在一个层次结构越来越复杂的模型，这些模型代表了一个渐进的更大的能力，网络进程“到达”整个网络通过长周期或半路径。我们认为，这类模型具有新的承诺，为网络和基于网络的过程的经验合理的模型的发展。
We argue that social networks can be modeled as the outcome of processes that occur in overlapping local regions of the network, termed local social neighborhoods. Each neighborhood is conceived as a possible site of interaction and corresponds to a subset of possible network ties. In this paper, we discuss hypotheses about the form of these neighborhoods, and we present two new and theoretically plausible ways in which neighborhood-based models for networks can be constructed. In the first, we introduce the notion of a setting structure, a directly hypothesized (or observed) set of exogenous constraints on possible neighborhood forms. In the second, we propose higher-order neighborhoods that are generated, in part, by the outcome of interactive network processes themselves. Applications of both approaches to model construction are presented, and the developments are considered within a general conceptual framework of locale for social networks. We show how assumptions about neighborhoods can be cast within a hierarchy of increasingly complex models; these models represent a progressively greater capacity for network processes to "reach" across a network through long cycles or semipaths. We argue that this class of models holds new promise for the development of empirically plausible models for networks and network-based processes.
