Data Sources and Bibliometric Collection
The 5th edition of the Research.com Best Mathematics Scientists in Israel Ranking primarily utilized data from OpenAlex and CrossRef, supplemented by multiple other reputable bibliometric sources. The bibliometric data used to devise the citation-based metrics underpinning the ranking were collected on January 12, 2026. Each scientist’s position within the ranking is determined by their D-index (Discipline H-index), a metric that includes only papers and citation data specifically related to the discipline under examination—in this case, Mathematics. This ensures discipline-specific relevance and accuracy in evaluating a researcher's impact.
Scope of Research and Qualification Criteria
A comprehensive examination was conducted on 279,971 scientist profiles sourced from a wide array of bibliometric databases, spanning all disciplines. Within this expansive dataset, 66 scientists specializing in Mathematics were identified and assessed. To qualify for inclusion in the ranking, scientists were required to meet a minimum D-index threshold of 30, and a majority of their tier publications needed to be in the area of Mathematics. Additionally, consideration was given to awards and significant achievements in the field, serving as supplementary indicators of scholarly excellence.
The D-index threshold reflects an increment of 10, calibrated against the estimated total number of scholars in each discipline. This scaling guarantees that the top 1% of leading researchers are represented in the ranking. Furthermore, a proximity threshold of 30% or less is maintained between a scientist’s general H-index and their D-index, ensuring consistent disciplinary impact.
Verification and Validation Practices
We recognize that raw bibliometric data should never serve as the sole criterion for evaluating scholarly output. In light of this, all scientist profiles underwent manual verification and were cross-correlated against publications indexed in a broad selection of trustworthy sources. While the number of papers published in prominent journals and conference proceedings does not directly influence position in the Research.com ranking, this metric serves as a valuable secondary signal of a scientist’s contribution to their research area.
The final ranking positions are established exclusively using each researcher’s D-index, derived from data curated through OpenAlex and CrossRef—two of the most authoritative and widely used bibliometric databases accessible to the research community at large.
