由组成范畴（正方形和桌子）组成一个联合范畴（方桌），传统上是通过形式集合相交来重塑的。在这个传统的观点中，范畴被视为精确定义的集合，当且仅当一个项目是两个组成范畴的成员时，它是联合范畴的成员。然而，正如现在人们普遍认为的那样，许多类别应该被视为有等级的，其成员在典型性和边界上都是不精确的。在本文中，我们认为集合交集不适合用于组合分级范畴。作者提出了另一种形式机制，其中通过形成值的联合分布，从组成类别构建联合类别。提出的模型考虑了联合类别中实例的隶属性和典型性，但仅当组成类别是独立的，或者它们之间的关系是已知的。（PsycINFO数据库记录(c) 2016 APA，版权所有）
Forming a conjoint category (square tables) from constituent categories (squares and tables) has traditionally been remodeled by formal set intersection. In this traditional view, in which categories are treated as precisely defined sets, an item is a member of the conjoint category if and only if it is a member of both constituent categories. However, as is now widely believed, many categories should be treated as graded, with members that vary in typicality and boundaries that are inexact. In the present article, it is argued that set intersection is inappropriate for combining graded categories. The authors propose an alternative formal mechanism in which a conjoint category is constructed from constituent categories by forming a joint distribution of values. The proposed model accounts for both membership and typicality of instances in conjoint categories, but only when the constituent categories are independent, or the relation between them is known.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
