Data Sources and Citation Metrics
The 5th edition of the Research.com Best Chemistry Scientists in Saudi Arabia Ranking is founded on comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, alongside multiple other reputable data repositories. The bibliometric records used in devising the citation-based metrics were collected on January 12, 2026. A scientist's position within the ranking is determined by their D-index (Discipline H-index), a refined metric that focuses exclusively on papers and citations relevant to the specific discipline under examination—in this case, Chemistry. This approach ensures a nuanced and discipline-specific evaluation of scholarly impact.
Scope of Research and Qualification Criteria
For this ranking, a total of 279,971 scientist profiles spanning all disciplines were initially examined from an extensive variety of bibliometric data sources. Within the domain of Chemistry, 86 scientists were specifically assessed. To qualify for inclusion, a scientist's D-index had to be a minimum of 40, with the majority of their tier publications concentrated in Chemistry. Additionally, scientists’ awards and documented achievements within the field of Chemistry were considered as supplemental indicators of distinction.
The D-index threshold for recognizing top researchers is dynamically set in increments of 10, reflecting the estimated total number of scholars in each discipline. This methodology guarantees that the top 1% of leading scholars in Chemistry are represented in the ranking. Moreover, there is a rigorously maintained proximity criterion where the difference between a scientist’s general H-index and their D-index must be 30% or less, ensuring alignment between their overall and discipline-specific scholarly influence.
Verification and Validation Process
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of a scholar’s output, the Research.com team undertook meticulous manual verification of all scientist profiles. Each profile was cross-correlated against publications documented in a broad spectrum of authoritative and trustworthy sources. While the number of publications in prominent journals and conference proceedings does not directly affect a researcher's ranking position, it constitutes an important complementary signal of a scientist’s research contributions within the Chemistry discipline.
The ranking positions are ultimately established based on each researcher’s D-index, derived from data aggregated through OpenAlex and CrossRef, the leading and most widely recognized bibliometric databases available to the global research community.
