Health professionals are faced with challenges when they have to exploit the semantics of concepts present in clinical terminologies in support of research activities. The difficulty lies in the fact that this semantics is represented not only through the labels of concepts, but also their position in the hierarchy, and, when available, their logical and textual definitions. We investigate and contrast the lexical, hierarchical, and logical representations of concepts in SNOMED CT through the example of Anemia and three other disorders. The four use cases we developed suggest that the lexical, hierarchical, and logical representations of concepts have a limited degree of overlap, but are complementary. Finally, we draw practical implications from our findings for SNOMED CT users and developers.
当健康专业人员必须利用临床术语中概念的语义来支持研究活动时，他们面临着挑战。困难在于，这种语义不仅通过概念的标签来表示，还通过它们在层次结构中的位置来表示，并且在可用时，还通过它们的逻辑和文本定义来表示。我们通过贫血和其他三种疾病的例子，研究并对比了SNOMED CT中概念的词汇、层次和逻辑表示。我们开发的四个用例表明，概念的词汇、层次和逻辑表示的重叠程度有限，但具有互补性。最后，我们从研究结果中为SNOMED CT的用户和开发者得出了实际的启示。
