2.1. Data Sources

The database from Web of Science (WOS) is used to administer a manuscript search for a scientometric review. We concentrated on the navigation of the entire citation network of the WOSCC database of subscription materials, which is regarded as one of the top databases of scholarly journals, books, and proceedings in the sciences, social sciences, and arts as well as humanities in the world. Major bibliographic sources, such as WOS, routinely include cited references, whereas other sources, such as PubMed and China National Knowledge Infrastructure (CNKI), do not include cited references [15]. Additionally, for these reasons and because of its wide coverage of different disciplines, as stated above, we focused on using WOS to retrieve scientific literature.
