Data Sources and Citation Metrics
The 5th edition of the Research.com Best Chemistry Scientists in Saudi Arabia Ranking is based primarily on citation and bibliometric data aggregated from OpenAlex and CrossRef, supplemented by multiple additional reputable data sources to ensure comprehensive coverage. The bibliometric data used to devise the citation-based metrics were collected on January 12, 2026. The ranking methodology centers on the D-index (Discipline H-index), which reflects a researcher’s impact within a specific discipline by considering only papers and citation metrics relevant to the examined field of Chemistry.
Scope of Research and Inclusion Criteria
The ranking was compiled from a broad dataset encompassing 279,971 scientist profiles identified through various bibliometric sources across all scientific disciplines. Of these, 85 scientists specializing in Chemistry within Saudi Arabia were examined in detail. To qualify for inclusion, a scientist’s D-index had to be at least 40, and the majority of their tier publications needed to be within the field of Chemistry. Additionally, consideration was given to notable awards and achievements in the Chemistry domain.
The threshold for the D-index is calibrated in increments of 10 relative to the estimated population of researchers per discipline, ensuring the inclusion of the top 1% of leading scholars. Furthermore, a maximum proximity of 30% is allowed between a scientist’s general H-index and their D-index to confirm disciplinary focus and high relevance of their output within Chemistry.
Verification Practices and Ranking Methodology
Understanding the limitations of raw bibliometric data as an absolute evaluation tool, extensive manual verification of all scientist profiles was undertaken. Profiles were cross-correlated with publications indexed in a wide range of trustworthy sources to ensure accuracy and authenticity. While the number of published papers in prominent journals and conference proceedings does not directly influence a researcher's rank, it serves as a valuable secondary indicator of their contributions to the scientific field.
The final position in the ranking is established using each researcher's D-index, based on data primarily derived from OpenAlex and CrossRef, two of the most prominent and widely recognized bibliometric databases available to the research community.
