The Unified Medical Language System(R) (UMLS) Metathesaurus contains records arranged by concept or meaning. Each concept contains a unique identifier (CUI) that can be used to track the concept over time. Since the January 2001 release, the Metathesaurus has included the file MRCUI that contains mappings for CUIs that disappear. This paper describes the processes that facilitated this effort and the ongoing effort to find suitable mappings for concepts whose meanings no longer exist in the Metathesaurus. This study highlights the need to identify missed synonymy prior to a release. It also shows a need to work more closely with source providers to identify the closest match in the Metathesaurus when they eliminate terms from their vocabularies.
统一医学语言系统(R)(UMLS)元词表包含按概念或含义排列的记录。每个概念都包含一个唯一标识符(CUI),可用于长期跟踪该概念。自2001年1月发布以来,元词表已包含文件MRCUI,其中包含已消失CUI的映射。本文描述了促成这项工作的过程以及为元词表中不再存在含义的概念寻找合适映射的持续努力。本研究强调了在发布之前识别遗漏同义词的必要性。它还表明需要与源提供者更密切合作,以便在他们从词汇表中删除术语时在元词表中确定最匹配的词。
