I previously developed methods for identifying cases of multiple synonymous concepts (redundancy) and concepts with multiple meanings (ambiguity) and applied them to the 1995 UMLS Metathesaurus. These methods use semantic approaches (including knowledge about word synonymy and the semantic types assigned to concepts) to complement the standard lexical approaches. In this paper, I describe the results of their application to the 2001 Metathesaurus and examine their implications for the evolution of the UMLS.
我之前开发了用于识别多个同义概念(冗余)和具有多种含义的概念(歧义)的方法,并将其应用于1995年的《统一医学语言系统元词表》。这些方法使用语义方法(包括关于词同义性的知识以及分配给概念的语义类型)来补充标准的词汇方法。在本文中,我描述了将这些方法应用于2001年元词表的结果,并研究了它们对《统一医学语言系统》演变的影响。
