摘要:

我们提出了一个大规模的比较五个多学科的书目数据源:Scopus,Web of Science,Dimensions,Crossref和Microsoft Academic。该比较考虑了这些数据来源所涵盖的2008-2017年期间的科学文件。Scopus以成对的方式与其他每个数据源进行比较。我们首先分析数据源之间在文档覆盖率方面的差异,例如,重点关注随时间的差异,每个文档类型的差异以及每个学科的差异。然后,我们研究了引文链接的完整性和准确性的差异。根据我们的分析,我们讨论了不同数据源的优点和缺点。我们强调的重要性相结合的全面覆盖的科学文献与一套灵活的过滤器,使选择的文献。

英文摘要:

We present a large-scale comparison of five multidisciplinary bibliographic data sources: Scopus, Web of Science, Dimensions, Crossref, and Microsoft Academic. The comparison considers scientific documents from the period 2008-2017 covered by these data sources. Scopus is compared in a pairwise manner with each of the other data sources. We first analyze differences between the data sources in the coverage of documents, focusing for instance on differences over time, differences per document type, and differences per discipline. We then study differences in the completeness and accuracy of citation links. Based on our analysis, we discuss strengths and weaknesses of the different data sources. We emphasize the importance of combining a comprehensive coverage of the scientific literature with a flexible set of filters for making selections of the literature.
