Previous bibliometric analyses of Medical Informatics' internal structure used MEDLINE records as the unit of study. EMBASE, a product of Excerpta Medica, carries a wider international scope and offers complementary retrieval results to MEDLINE. Since much medical informatics critical thinking originated abroad and migrated to North America, this difference in coverage may also indicate a different perspective of "what constitutes medical informatics." Using traditional bibliometric and multivariate data analysis techniques, the present work examines EMBASE indexing records for the same 1995-1999 time frame as earlier MEDLINE studies to identify and compare structural features of the field.
先前对医学信息学内部结构的文献计量分析以MEDLINE记录作为研究单位。EMBASE是《医学文摘》（Excerpta Medica）的一个产品，其国际范围更广，并能提供与MEDLINE互补的检索结果。由于许多医学信息学的批判性思维起源于国外并传播到北美，这种覆盖范围的差异可能也表明了对于“什么构成医学信息学”的不同观点。运用传统的文献计量和多变量数据分析技术，本研究考察了与早期MEDLINE研究相同的1995 - 1999年时间框架内的EMBASE索引记录，以识别和比较该领域的结构特征。
