CWTS provides bibliometric data and analyses based on its citation index system. Our tailor-made study design makes it possible to analyse at the level of a discipline, research field or organisational unit. We offer a broad range of analytical dimensions because we have a plethora of (interconnected) data sources in our citation index system.

CWTS Integrated Database System

The core of this system comprises four major bibliographic databases: OpenAlex, Web of Science Core Collection, Dimensions and Scopus. By sophisticated data integration efforts, we have massively expanded our database system with the following databases: PATSTAT (patents), Unpaywall (open access), Crossref (publications), Crossref Event Data (altmetrics), DataCite (data sets), ORCID (researchers), ROR (organizations), Altmetric (altmetrics), PubMed (biomedical publications), Mendeley (readership) and Overton (policy documents, guidelines). We leverage on this rich combination of data sources to deliver high-quality analytics and provide more valuable insights for research evaluation and research management purposes.

State-of-the-art bibliometric performance- and benchmark analysis

CWTS serves its clients with bibliometric data and quantitative analyses of research performance. The performance can be analysed along a vast range of analytical dimensions because we work with all major scientific databases. We assess, for example, the following dimensions: publication output, citation impact, collaboration, open access publishing, gender, workforce composition, societal impact and multidisciplinarity. Moreover, we can provide an international comparative perspective in which several institutes or countries can be included.
