本文描述了将临床概念表达和编码为基本实体组合的几种方法，并描述了一种基于 SNOMED RT 的方法，该方法可以允许临床术语工作的进一步融合。我们解释了先前组合概念表示方法的缺点，以及 SNOMED 当前方法采用基于描述逻辑 (DL) 的基础的原因。 DL模型有很多优点：它为SNOMED断言建立了形式语义并建议了语法；它通过与 DL 的已知结果相对应，为理解表达性和计算复杂性提供了基础；它有助于澄清 SNOMED、NHS 临床术语（以前的 Read Codes）和 GALEN 中现有概念表示方法之间的关系，使趋同之路更加清晰。
This paper describes several approaches to the expression and coding of clinical concepts as composites of elementary entities, and describes an approach based on SNOMED RT that may permit further convergence of clinical terminology efforts. We explain the shortcomings of previous approaches to compositional concept representation, as well as the reasons for SNOMED's current approach, which adopts a foundation based in description logics (DLs). The DL model has many advantages: it establishes a formal semantics for SNOMED assertions and suggests a syntax; it provides a basis for understanding expressiveness and computational complexity, through correspondence with known results from DLs; and it helps to clarify the relationships among existing concept representation methods in SNOMED, NHS Clinical Terms (formerly the Read Codes), and GALEN, making a path to convergence more clear.
