Each university's standing in the ranking is determined by the aggregate sum of D-indexes (Discipline H-index) belonging to all ranking scholars affiliated with the institution. The D-index metric is discipline-specific, including only publications and citation data pertinent to the examined research area, yet the ranking embraces scientists from all major research disciplines to present a truly comprehensive evaluation.
Scope of Research and Scientist Inclusion Criteria
This edition rigorously assessed 279,971 scientist profiles identified through a diverse set of bibliometric data sources, spanning all major scientific disciplines. To ensure high quality and meaningful contributions, only scientists with a qualifying D-index threshold of 20 or above were considered. Besides bibliometric metrics, scientists’ professional accolades, awards, and achievements within their fields were also evaluated to capture their broader impact and leadership.
Verification Practices and Data Integrity
Recognizing that raw bibliometric data alone cannot fully encapsulate the quality or impact of scholarly output, the researchers behind this ranking undertook extensive manual verification of all scientist profiles. Each profile was meticulously cross-correlated against publications listed in a broad range of trustworthy sources to confirm accuracy and authenticity.
While the quantity of papers published in prominent journals and leading conference proceedings is not a direct factor influencing the ranking positions, this metric serves as a valuable secondary signal of a scientist’s research contributions within their discipline.
The ranking positions themselves are derived using each researcher’s H-index, based on data consolidated mainly from OpenAlex and CrossRef. Both are recognized as the most prominent and reliable bibliometric databases accessible to the global research community.
