许多描述社会网络结构属性的方法都涉及到社会地位和社会角色的双重概念。这些方法的共同目标是以简化的形式表示复杂社会网络数据中的模式，揭示类似地嵌入关系网络中的行为者集合，并描述多关系社会网络中关系之间的关联。这些表示通常采用块模型的形式。在块模型中，参与者被分配到位置，并且网络关系被呈现在位置之间，而不是参与者之间。关于块模型的文献非常广泛，并且充斥着块模型的计算和应用。然而，令人惊讶的是，对区块模型分析的两个非常重要的方面缺乏关注：结果的解释和评估。本文的目的是聚焦于这些主题，主要是对目前使用的口译和评价方法进行回顾和综合。
Many methods for the description of social network structural properties are concerned with the dual notions of social position and social role. Common goals of these methods are to represent patterns in complex social network data in simplified form, to reveal sets of actors who are similarly embedded in networks of relations, and to describe the associations among relations in multirelational social networks. Often these representations take the form of a blockmodel. In a blockmodel actors are assigned to positions and network relations are presented among positions, rather than among actors.The literature on blockmodels is extensive and is overflowing with computation and applications of blockmodels. However, there is a surprising lack of attention to two very important aspects of block-model analyses: the interpretation and evaluation of the results. The purpose of this paper is to focus on these topics, primarily reviewing and synthesizing the approaches to interpretation and evaluation currently in use.
