Data Sources and Ranking Metrics
The 5th edition of the Research.com Best Mathematics Scientists in Turkey Ranking is primarily based on comprehensive bibliometric data sourced from OpenAlex and CrossRef, alongside multiple additional reputable databases. The citation-based metrics that underpin the ranking were collected on January 12, 2026, ensuring the use of the most current and robust information available. A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a refined metric that considers only the papers and citation metrics relevant to the examined discipline—in this case, Mathematics—thereby providing a focused and discipline-specific assessment of research impact.
Scope of Research and Inclusion Criteria
The ranking evaluates a carefully curated pool of 279,971 scientist profiles examined across all disciplines with a particular focus on 30 scientists specialized in Mathematics within Turkey. To qualify for inclusion in the ranking, a scientist’s D-index must be at least 30, and the majority of their tier publications should be within the mathematical sciences. Additionally, awards and notable achievements pertinent to Mathematics were factored into the evaluation process to complement bibliometric data.
The D-index threshold for identifying top researchers is dynamically set as increments of 10, proportional to the estimated total number of scholars within each discipline. This methodology ensures the inclusion of the top 1% of leading scholars in the respective fields. Moreover, eligibility mandates that the proximity between a scientist’s general H-index and their D-index is within 30% or less, thereby affirming a strong alignment of their research impact within Mathematics specifically.
Verification Practices and Methodological Rigor
The research team behind this ranking fully acknowledges that raw bibliometric data alone cannot serve as an absolute measure of a scholar’s output or impact. Consequently, all scientist profiles underwent meticulous manual verification, complemented by cross-correlation against publications from a broad spectrum of trustworthy academic and professional sources.
Although not a direct factor affecting the ranking position, the number of papers published in prominent journals and conference proceedings has been recognized as a valuable secondary signal of a scientist’s contributions to their specific scientific domain.
Positions in the ranking are ultimately established using each researcher’s D-index, based on verified data from OpenAlex and CrossRef, which remain the most prominent and widely recognized bibliometric databases accessible to the global research community.
