The ESI database is an analytical database established by Clarivate based on the aggregation and analysis of scientific literature and their cited references collected in the Web of Science Core Collection (SCIE/SSCI) over the past 10 years. It is categorized as a factual database. ESI assists researchers in specifically analyzing international scientific literature to understand the development and impact of target researchers, research institutions, countries/regions, and academic journals in a particular scientific field, as well as identifying research frontiers. Additionally, research managers can use ESI to find objective data that aids in decision-making analysis.
