The disorder chapter of Version 3 of the Read codes is a rich source of clinically derived terminology. The file structure has been designed to meet a clinical need to support both enumerated and compositional taxonomy. This requirement coupled with the maintenance of multiple classification necessitates a mechanism to identify consistent hierarchical placement and equivalence between concepts. The early work on the semantic definition of the disorder chapter, to support these requirements, is outlined and the attributes that have been found to be important are presented. We also describe different categories of completeness of definition that have been identified, and the scope of those that are likely to remain incompletely characterised.
《Read编码》第3版中的疾病章节是临床衍生术语的丰富来源。文件结构的设计旨在满足支持枚举式和组合式分类法的临床需求。这一要求加上多种分类的维护，需要一种机制来确定概念之间一致的层次结构位置和等效性。本文概述了为支持这些要求而在疾病章节语义定义方面的早期工作，并介绍了已发现的重要属性。我们还描述了已确定的不同定义完整性类别，以及可能仍未完全表征的类别范围。
