OBJECTIVE
A general framework for representation of clinical data that provides a declarative semantics of terms and that allows developers to define explicitly the relationships among both terms and combinations of terms.
DESIGN
Use of conceptual graphs as a standard representation of logic and of an existing standardized vocabulary, the Systematized Nomenclature of Medicine (SNOMED International), for lexical elements. Concepts such as time, anatomy, and uncertainty must be modeled explicitly in a way that allows relation of these foundational concepts to surface-level clinical descriptions in a uniform manner.
RESULTS
The proposed framework was used to model a simple radiology report, which included temporal references.
CONCLUSION
Formal logic provides a framework for formalizing the representation of medical concepts. Actual implementations will be required to evaluate the practicality of this approach.
目的
一种临床数据表示的通用框架，该框架提供术语的声明性语义，并允许开发者明确地定义术语以及术语组合之间的关系。
设计
使用概念图作为逻辑的标准表示，并使用现有的标准化词汇表——医学系统命名法（国际医学术语系统命名法，SNOMED International）作为词汇元素。诸如时间、解剖结构和不确定性等概念必须以一种能够将这些基础概念与表面层次的临床描述以统一方式关联起来的方式进行显式建模。
结果
所提出的框架被用于对一份包含时间参考的简单放射学报告进行建模。
结论
形式逻辑为医学概念表示的形式化提供了一个框架。需要实际的实现来评估这种方法的实用性。
