A scientist's ranking position is determined by their D-index (Discipline H-index), a refined bibliometric indicator that exclusively considers papers and citation metrics within the examined discipline—in this case, Chemistry. This discipline-specific focus enables a more accurate assessment of a researcher's impact and contributions within their specialized field.
Scope of Research and Selection Criteria
In structuring the ranking, a total of 279,971 scientist profiles spanning all disciplines were initially reviewed from a diverse array of bibliometric data sources. From this extensive dataset, 98 scientists specializing in Chemistry in the Czech Republic were identified and assessed in detail.
To qualify for inclusion in the ranking, a scientist’s D-index was required to be at least 40, effectively establishing a rigorous baseline for research impact within Chemistry. Additionally, the majority of the scientist’s tier publications needed to be within the Chemistry domain, ensuring discipline relevance. Consideration was also given to honors and awards received specifically for achievements in the field of Chemistry.
The threshold for the D-index is not static but set in increments of 10, calibrated to accommodate the estimated total number of scholars in each discipline. This approach guarantees the inclusion of the top 1% of leading researchers in the respective field. Furthermore, candidates’ general H-index and D-index were examined to confirm a proximity of 30% or less, ensuring their impact is strongly tied to their Chemistry research rather than general scholarly output.
Additional Verification Practices
Recognizing that raw bibliometric data alone can never provide a definitive measure of a scholar’s research quality or contribution, the Research.com team undertook meticulous manual verification of all scientist profiles. Each profile was cross-checked against publications in a broad range of trustworthy sources to validate accuracy and relevance.
Although the number of publications in prominent journals and conference proceedings does not directly influence the researcher’s position in the ranking, it serves as a valuable secondary indicator of a scientist’s stature and contribution within their specific research area.
The ranking positions are ultimately established based on the rigorously calculated D-index, drawing from data aggregated primarily from OpenAlex and CrossRef—currently the most prominent and widely respected bibliometric databases accessible to the global research community.
