A crucial component of a medical concept representation system is the classifier. It requires features that are not sufficiently supported by current logic based formalisms like description logics and conceptual graphs. Those features are, for instance, the representation of partitive and spatial relations and their impact on subsumption. This paper introduces graph oriented classification operators for a concept representation language with normal forms. Emphasis is on the separation of generic and partitive relations and on the mutual interdependence of subsumption and part-whole. For that purpose operators are given for formal subsumption, formal part-whole, subsumptive part-whole and part-sensitive subsumption. These operators are based on the formal structure of concept descriptions and on explicitly introduced generic and partitive relationships between their constituents.
医学概念表示系统的一个关键组件是分类器。它需要一些当前基于逻辑的形式体系（如描述逻辑和概念图）无法充分支持的特征。例如，这些特征包括部分关系和空间关系的表示及其对包含关系的影响。本文针对一种具有范式的概念表示语言引入了面向图的分类运算符。重点在于一般关系和部分关系的分离以及包含关系与整体 - 部分关系的相互依存性。为此，给出了形式包含、形式整体 - 部分、包含性整体 - 部分和部分敏感包含的运算符。这些运算符基于概念描述的形式结构以及其组成部分之间明确引入的一般关系和部分关系。
