An institution’s position in the ranking is determined by a summative measure of D-indexes (Discipline H-index) for all ranking scholars whose primary publication area is Chemistry and are affiliated with that institution. Notably, the D-index is a highly discipline-specific variant of the H-index, restricted exclusively to publications and citations within the field of Chemistry, thus providing a field-appropriate evaluation of research impact.
Scope of the Research Analysis
For the current edition, a total of 279,971 scientist profiles were identified using various bibliometric data sources, and from this pool, 279,971 Chemistry-specific scientists were rigorously analysed. To maintain a high standard of inclusion, the qualifying D-index threshold was set at 40, with a requirement that the preponderance of each scholar’s significant publications fell within Chemistry. Additionally, individual awards and achievements in the discipline were taken into account to enrich the evaluation.
For top-level researchers, the D-index threshold is incremented by 10 based on the estimated total number of scholars in each discipline, ensuring that at least the top 1% of leading scholars are included. A proximity criterion was also enforced, limiting the discrepancy between a scientist’s general H-index and their Chemistry-specific D-index to less than 30%, which guarantees disciplinary relevance. Evaluations further considered recognized awards and achievements, reinforcing the robustness and selectivity of the ranking methodology.
Verification Practices and Data Validation
The team at Research.com recognizes the inherent limitations of raw bibliometric data as an evaluative instrument. Consequently, all scholar profiles underwent thorough manual verification, where data was cross-checked against a broad set of reliable publication databases. While the sheer number of papers in prominent journals and conference proceedings is not a direct factor in the ranking, it serves as a valuable secondary indicator of a scholar’s contribution and stature within the discipline.
The final placement in the ranking is determined via each researcher’s H-index strictly for Chemistry, as obtained from OpenAlex and CrossRef—the most prominent and respected bibliometric databases serving the global research community today.
