一个算法派生的抽象网络，称为局部区域分类，为SNOMED层次结构，导致识别的概念被认为是复杂的。“复合体”的名称是根据对局部区域分类法的组成概念组之间重叠的结构分析自动得出的。这种复杂的概念，称为重叠概念，构成了层次结构的混乱部分，并且可能成为试图理解层次结构内容的用户的障碍。提出了一种新的方法，用于将重叠概念的整个集合划分为单根组，这些组更易于管理和理解。不同种类的重叠概念具有不同程度的复杂性被确定。这就产生了一个重叠概念的抽象模型，称为不相交部分区域分类法，它可以作为增强的高级别显示的工具。该方法被证明与应用程序SNOMED的标本层次结构。总体而言，由此产生的不相交的局部区域分类提供了一个细化的层次结构的组织和概念内容，可以帮助用户，如维护人员，与SNOMED工作。实用的不相交的局部区域分类法作为基础的SNOMED审计方案中的一个配套文件。
An algorithmically-derived abstraction network, called the partial-area taxonomy, for a SNOMED hierarchy has led to the identification of concepts considered complex. The designation “complex” is arrived at automatically on the basis of structural analyses of overlap among the constituent concept groups of the partial-area taxonomy. Such complex concepts, called overlapping concepts, constitute a tangled portion of a hierarchy and can be obstacles to users trying to gain an understanding of the hierarchy’s content. A new methodology for partitioning the entire collection of overlapping concepts into singly-rooted groups, that are more manageable to work with and comprehend, is presented. Different kinds of overlapping concepts with varying degrees of complexity are identified. This leads to an abstract model of the overlapping concepts called the disjoint partial-area taxonomy, which serves as a vehicle for enhanced, high-level display. The methodology is demonstrated with an application to SNOMED’s Specimen hierarchy. Overall, the resulting disjoint partial-area taxonomy offers a refined view of the hierarchy’s structural organization and conceptual content that can aid users, such as maintenance personnel, working with SNOMED. The utility of the disjoint partial-area taxonomy as the basis for a SNOMED auditing regimen is presented in a companion paper.
