目前，统一医学语言系统（UMLS）中包含的编码方案都不足以表达医学进展记录。一些编码方案遭受域不完整性，另一些遭受无法表示修饰符和时间参考，还有一些遭受这两个问题。最近发布的系统化医学名词（SNOMED III）的版本是一个潜在的解决方案的数据表示问题，因为它是相对完整的域，因为它使用的生成编码方案，将允许建设的代码，包含修改器和时间参考。然而，SNOMED III确实有一个重要的弱点。SNOMED III缺乏使用其代码的正式系统;因此，它无法确保不同机构使用代码的一致性。应用概念图形式主义的SNOMED III可以确保这种使用的一致性。概念图形式主义也将允许映射的结果SNOMED III代码到关系数据模型和其他正式的系统，如一阶谓词演算。
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.
