Positions in this ranking are determined by the cumulative sum of D-indexes (Discipline H-index) of all ranking scholars affiliated with each institution. The D-index quantifies scholarly impact exclusively within a specific discipline by incorporating publications and citation data relevant to that field. Importantly, the evaluation considered scientists across all major research areas, providing a holistic and balanced assessment of institutional research excellence.
Scope of Research and Inclusion Criteria
The ranking’s scope encompasses 279,971 scientist profiles identified through a diverse array of bibliometric data sources, covering all major scientific disciplines. To qualify for inclusion, individual scientists were required to have a minimum D-index of 20, ensuring that the ranking reflects researchers with demonstrated influence and productivity in their respective fields.
In addition to bibliometric thresholds, scientists’ awards and notable achievements within their disciplines were taken into account, further validating the relevance and quality of the included scholars. This multi-factor approach promotes a richer and more nuanced evaluation of scientific contributions.
Verification and Quality Control Measures
The Research.com team recognizes that raw bibliometric data alone do not capture the full extent of scholarly impact and therefore undertook rigorous additional verification practices. Each scientist’s profile was manually verified and cross-correlated against publications indexed in a broad range of trustworthy sources to ensure accuracy and reliability.
Although the number of publications in leading journals and conference proceedings does not directly influence ranking positions, it serves as an essential secondary indicator of a researcher’s contribution and prominence in their specific area of science.
The ranking positions themselves are established based on each researcher’s H-index, using data sourced primarily from OpenAlex and CrossRef — two of the most prominent and widely respected bibliometric databases accessible to the research community today.
