A scientist's position in the ranking is determined by their D-index (Discipline H-index), a refined variant of the traditional H-index that only incorporates papers and citation metrics pertinent to the specific discipline under examination—in this case, Chemistry. This approach ensures that the ranking reflects a researcher’s impact and productivity within their specialized field rather than their broader scientific output.
Scope of Research and Eligibility Criteria
The ranking examined a total of 279,971 scientist profiles identified across multiple bibliometric data sources covering all disciplines, of which 4,370 scientists were specifically identified as active contributors in the field of Chemistry.
To qualify for inclusion, scientists were required to have a minimum D-index of 40, with the majority of their tier publications concentrated in Chemistry. Additionally, recognition of awards and notable achievements within the field were factored into the evaluation process. The D-index threshold for considering top researchers is calibrated in increments of 10 according to the estimated total number of scholars per discipline, ensuring that the top 1% of leading scholars are incorporated in the list. A further stipulation is that the proximity between a scientist’s overall general H-index and their Chemistry-specific D-index does not exceed 30%, thus reinforcing a strong alignment of their impact within the discipline.
Verification and Validation Processes
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output, the ranking team undertook rigorous manual verification of all scientist profiles. This involved cross-correlating the bibliometric information with publications indexed in a broad range of trustworthy and authoritative sources to ensure accuracy and integrity of the data.
While not a direct component influencing a researcher’s position in the Research.com ranking, the volume of papers published in prominent journals and conference proceedings serves as an important secondary indicator of a scientist’s contribution to research within Chemistry. The primary ranking position, however, is decisively based on each researcher's D-index, calculated using data gathered principally from OpenAlex and CrossRef—both recognized globally as the most prominent and reliable bibliometric databases accessible to the research community.
