To see whether the National Library of Medicine's Metathesaurus (tm) includes terminology relevant to clinical nursing practice, two widely used nursing vocabularies were matched against the Meta. The two nursing vocabularies are 1) the North American Nursing Diagnosis List of Approved Diagnoses; and 2) the Omaha System, a vocabulary of problems and interventions developed by the Omaha Visiting Nurses Association. First, the terms were scanned against Meta in their "native" form, with phrases and combinations intact. This produced a relatively low percentage of exact matches (12%). Next, the terms were separated into "core concepts" and "modifiers" and the analysis was repeated. The percentage of exact matches to terms in Meta increased to 32%. However, the semantic types of the split terms often were not equivalent to the semantic types of the phrases from which the split terms were derived; also, in some cases, terms returned as exact matches had different meanings in Meta. Automatic scanning for lexical matches is a helpful first step in searching for vocabulary representation in Meta, but term-by-term search for context, semantic type and definition is essential. However, it seems clear that representation of nursing terminology in the Metathesaurus needs to be expanded.
为了确定美国国立医学图书馆的叙词表是否包含与临床护理实践相关的术语，将两种广泛使用的护理词汇与该叙词表进行了匹配。这两种护理词汇分别是：1）北美护理诊断认可清单；2）奥马哈系统，这是由奥马哈访视护士协会开发的关于问题和干预措施的词汇表。首先，以词汇的“原始”形式在叙词表中进行扫描，短语和组合保持完整。这样得到的完全匹配百分比相对较低（12%）。接下来，将词汇分为“核心概念”和“修饰词”，并重复进行分析。与叙词表中词汇的完全匹配百分比提高到了32%。然而，拆分后的词汇的语义类型往往与从中拆分出这些词汇的短语的语义类型不相等；而且，在某些情况下，作为完全匹配返回的词汇在叙词表中的含义有所不同。自动扫描词汇匹配是在叙词表中搜索词汇表示的有用的第一步，但逐词搜索上下文、语义类型和定义至关重要。然而，显然叙词表中护理术语的表示需要扩充。
