An institution's position in the ranking is determined by the aggregated D-indexes (Discipline H-index) of all affiliated scholars who meet the eligibility criteria. The D-index is a metric that includes exclusively publications and citation data for a specified discipline. While this approach ensures depth within each academic field, it also captures scholars from all major research areas, reflecting the comprehensive scope of research excellence across institutions.
Scope of Research Evaluation
The ranking's foundation lies in the thorough evaluation of 279,971 scientist profiles, identified from a diverse range of bibliometric databases. These profiles cover all major scientific disciplines, ensuring a holistic view of academic achievement.
For inclusion in the analysis, each scientist was required to meet a minimum D-index threshold of 20, ensuring that only researchers with demonstrated impact in their field contribute to their institution’s standing. In addition to the bibliometric criteria, the ranking also factored in notable awards and professional achievements within each scholar's field of study to further recognize academic excellence.
Verification and Data Integrity Practices
The Research.com team recognizes that raw data, while invaluable, should not be viewed as an absolute measure of scholarly output. To address this, every scientist profile in the ranking underwent manual verification and was cross-correlated against publication records in a broad array of reputable sources.
Although not a direct factor in determining ranking positions, the volume of publications in leading journals and conference proceedings is acknowledged as a meaningful secondary indicator of a scientist’s contribution to their domain.
The final position in the ranking is established using each researcher’s H-index, as curated from OpenAlex and CrossRef—currently the most reputable and widely adopted bibliometric databases available to the academic community.
