A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a specialized metric that selectively includes papers and citations exclusively within the examined discipline—in this case, Chemistry. This ensures that each researcher’s impact is measured by their contributions strictly related to their field of expertise, enhancing the accuracy and relevance of the ranking.
Scope of Research and Qualification Criteria
The ranking methodology involved an exhaustive evaluation of 279,971 scientist profiles identified across a variety of bibliometric data sources and encompassing all academic disciplines. Within this extensive dataset, 16 scientists specializing in Chemistry from the United Arab Emirates were distinctly examined for inclusion in the ranking.
To qualify for the ranking, a scientist’s D-index had to meet a minimum threshold of 40, with the majority of their tier-level publications being firmly rooted in the field of Chemistry. Additionally, the assessment considered notable awards and achievements relevant to the discipline, providing a qualitative dimension to the evaluation process.
The D-index threshold is dynamically set in increments of 10, proportional to the estimated total number of researchers in each discipline. This approach ensures consistent representation of the top 1% of leading scholars within their respective fields. Furthermore, there is an established proximity criterion requiring the difference between a scientist’s general H-index and their D-index to be 30% or less, guaranteeing that the disciplinary impact aligns closely with overall research influence.
Additional Verification Practices
Recognizing the limitations of raw bibliometric data as an absolute measure of scholarly impact, the Research.com team undertook meticulous manual verification of all scientist profiles. Each profile was cross-correlated against publications indexed in a broad array of trustworthy and authoritative sources to confirm accuracy and validity.
While the quantity of papers published in prominent journals and conference proceedings does not directly influence a researcher’s position in the ranking, it serves as a valuable secondary indicator of their contribution to advancing knowledge within their scientific domain.
The position in the ranking is primarily established using each researcher’s D-index derived from data collected from OpenAlex and CrossRef—two of the most prominent and widely recognized bibliometric databases accessible to the global research community.
