目的：本研究的目的是从研究评估的角度评估科学文献在Scopus和Web of Science中的覆盖率。设计/方法论/方法：挪威学术界已就研究评估和资助背景下哪些应被列为原创研究出版物的某些标准达成一致。自2004年以来，挪威科学索引(NSI)在一个综合书目数据库中应用了这些标准。从出版类型、研究领域和语言等方面对Scope us和Web of Science的相对覆盖率进行了比较。研究结果：我们的结果显示，2015年和2016年，Scope us覆盖了挪威科学和学术出版物总产出的72%，而Web of Science核心馆藏的相应数字为69%。覆盖范围最广的是医学和健康(89%和87%)以及自然科学和技术(85%和84%)。社会科学(48%在SCopus中，40%在Web of Science核心收藏中)，特别是人文学科(27%和23%)在这两个国际数据源中的涵盖要少得多。研究限制：与只有一个国家的数据进行比较是研究的局限性，但用于定义一个国家的科学产出以及在Scope和Web of Science中识别依赖于领域的部分表示模式的标准应该是可识别的，并且对其他国家也是有用的。原创性/价值：本研究的新颖性是基于标准的方法来研究这两个数据源的覆盖问题。
Purpose: The purpose of this study is to assess the coverage of the scientific literature in Scopus and Web of Science from the perspective of research evaluation.Design/methodology/approach: The academic communities of Norway have agreed on certain criteria for what should be included as original research publications in research evaluation and funding contexts. These criteria have been applied since 2004 in a comprehensive bibliographic database called the Norwegian Science Index (NSI). The relative coverages of Scopus and Web of Science are compared with regard to publication type, field of research and language.Findings: Our results show that Scopus covers 72 percent of the total Norwegian scientific and scholarly publication output in 2015 and 2016, while the corresponding figure for Web of Science Core Collection is 69 percent. The coverages are most comprehensive in medicine and health (89 and 87 percent) and in the natural sciences and technology (85 and 84 percent). The social sciences (48 percent in Scopus and 40 percent in Web of Science Core Collection) and particularly the humanities (27 and 23 percent) are much less covered in the two international data sources.Research limitation: Comparing with data from only one country is a limitation of the study, but the criteria used to define a country's scientific output as well as the identification of patterns of field-dependent partial representations in Scopus and Web of Science should be recognizable and useful also for other countries.Originality/value: The novelty of this study is the criteria-based approach to studying coverage problems in the two data sources.
