A scientist’s position in the ranking is determined by their D-index (Discipline H-index). Unlike the traditional H-index, the D-index exclusively incorporates publications and citation metrics pertinent to the specific discipline under examination — in this case, Engineering and Technology — providing a focused evaluation of each researcher's contributions in their primary area of expertise.
Scope and Criteria of the Ranking
The ranking assesses a total of 279,971 scientist profiles identified from a spectrum of bibliometric sources, encompassing all scientific disciplines. Specifically, 73 scientists from the field of Engineering and Technology in Israel were evaluated for inclusion in this edition.
To qualify for the ranking, a scientist's D-index must be at least 30, with a majority of their tier publications occurring within the Engineering and Technology discipline. Additionally, an individual’s awards and notable achievements within the field were taken into account to complement the bibliometric evaluation.
The threshold for the D-index varies in increments of 10 relative to the overall estimated number of scholars in each discipline, a measure designed to include the top 1% of leading researchers without artificially narrowing the candidate pool. Furthermore, to ensure discipline-specific relevance, the difference between a scientist’s general H-index and their D-index is maintained within a proximity of 30% or less.
Verification and Validation Practices
The Research.com team recognizes that raw bibliometric data alone cannot serve as an absolute measure of scholarly contribution. Consequently, all scientist profiles underwent meticulous manual verification. Cross-referencing was conducted against a wide array of trustworthy sources to confirm the accuracy of publication records and citation counts.
While the quantity of publications in prestigious journals and conference proceedings does not directly influence the ranking position, it serves as a valuable secondary indicator of a researcher’s impact and contribution to their scientific community.
The ranking positions themselves are established strictly based on each scientist’s D-index, relying on data acquired from OpenAlex and CrossRef — two of the most well-known and extensively utilized bibliometric databases accessible to researchers globally.
