目的:探讨MEDLINE检索中缩略语和首字母缩略词的使用对引文检索的影响。方法:检索MEDLINE中20个常用医学缩略语,每个缩略语至少有400条引文。在MEDLINE主题检索中输入每个缩写,以确定其是否映射到适当的医学主题词(MeSH)术语。记录MeSH类别和检索到的引文数量。缩写及其定义分别输入单独的文本单词检索,并记录检索到的引文数量。合并数据集,以确定检索中检索到的相同和唯一引文的数量。结果:MEDLINE识别了所有20个缩写,并将其映射到适当的MeSH标题。然而,MeSH术语分配可能是大小写和空格敏感的,MeSH术语搜索比文本词搜索检索到更多的引文,20个缩写中有18个。对每种搜索方法产生的文档集进行比较,发现了每种方法共有的引文子集。虽然检索到的所有数据集都显示重叠,但没有两个数据集是完全相同的。此外,每个引文集都包含一定比例的独特文件。结论:检索所有独特的引文需要三次检索;主题与缩写,文本词与缩写,文本词与定义。这些结果对MEDLINE具有重要意义。用户.
Objective: To determine the effect of the use of abbreviations and acronyms on citation retrieval in MEDLINE searches. Methods: Twenty common medical abbreviations that retrieved a minimum of 400 citations each in MEDLINE text, word searches were studied. Each abbreviation was entered in a MEDLINE subject search to determine whether it mapped to an appropriate medical subject heading (MeSH) term. The MeSH category and the number of citations retrieved were recorded. The abbreviation and its definition were each entered in separate text word searches, and the number of citations retrieved was recorded. Sets were combined to determine the number of identical and unique citations retrieved in the searches. Results: MEDLINE recognized all 20 abbreviations and mapped them to appropriate MeSH headings. MeSH term assignment, however, may be case- and space-sensitive, MeSH term searches retrieved more citations than text word searches for 18 of 20 abbreviations. Comparison of the document sets yielded by each search method revealed a subset of citations common to each. Although all sets retrieved showed overlap, no two were identical. In addition, each citation set contained a proportion of unique documents. Conclusion: Retrieval of all unique citations required three searches; subject with abbreviation, text word with abbreviation, and text word with definition. These results have important implications for MEDLINE. users.
