None of the coding schemes currently contained within the Unified Medical Language System (UMLS) is sufficiently expressive to represent medical progress notes adequately. Some coding schemes suffer from domain incompleteness, others suffer from the inability to represent modifiers and time references, and some suffer from both problems. The recently released version of the Systematized Nomenclature of Medicine (SNOMED III) is a potential solution to the data-representation problem because it is relatively domain complete, and because it uses a generative coding scheme that will allow the construction of codes that contain modifiers and time references. SNOMED III does have an important weakness, however. SNOMED III lacks a formalized system for using its codes; thus, it fails to ensure consistency in its use across different institutions. Application of conceptual-graph formalisms to SNOMED III can ensure such consistency of use. Conceptual-graph formalisms will also allow mapping of the resulting SNOMED III codes onto relational data models and onto other formal systems, such as first-order predicate calculus.
统一医学语言系统（UMLS）目前包含的编码方案中，没有一种能够充分表达医学病程记录。一些编码方案存在领域不完整性问题，另一些则无法表示修饰词和时间参考，还有一些则同时存在这两个问题。最近发布的医学系统命名法（SNOMED III）版本是数据表示问题的一个潜在解决方案，因为它相对领域完整，并且使用了一种生成式编码方案，能够构建包含修饰词和时间参考的代码。然而，SNOMED III确实有一个重要的弱点。SNOMED III缺乏使用其代码的形式化系统；因此，它无法确保在不同机构间使用的一致性。将概念图形式主义应用于SNOMED III可以确保这种使用的一致性。概念图形式主义还将允许将生成的SNOMED III代码映射到关系数据模型和其他形式系统上，如一阶谓词演算。
