Controlled medical vocabularies are useful in application areas such as medical information-systems and decision-support. However, such vocabularies are large and complex, and working with them can be daunting. It is important to provide a means for orienting users to the vocabulary's contents. This paper introduces a methodology for partitioning a vocabulary into small, meaningful pieces. The partitioning is done with respect to the vocabulary's IS-A hierarchy. The methodology, based on a set of rules for refining the IS-A hierarchy, is a process carried out by a user in conjunction with the computer. The methodology is demonstrated on a complex portion of a vocabulary.
受控医学词汇表在诸如医学信息系统和决策支持等应用领域中很有用。然而，这类词汇表规模大且复杂，使用起来可能让人望而生畏。为用户提供一种了解词汇表内容的方法很重要。本文介绍了一种将词汇表划分为小的、有意义的部分的方法。划分是根据词汇表的“是一个”层次结构进行的。该方法基于一组细化“是一个”层次结构的规则，是用户与计算机协同执行的过程。该方法在词汇表的一个复杂部分上进行了演示。
