A scientist’s position within this ranking is determined using the D-index (Discipline H-index), a refined bibliometric metric that considers only papers and citation records relevant to the discipline under examination—specifically Engineering and Technology for this ranking. This ensures an accurate representation of a researcher’s influence within their specific area of expertise.
Scope and Criteria of the Ranking
For the creation of this ranking, an extensive dataset was synthesized, encompassing 279,971 scientist profiles identified across diverse bibliometric repositories spanning all scientific disciplines. Within this cohort, a focused subset of scientists specializing in Engineering and Technology was identified and analyzed.
- To qualify for inclusion in the ranking, scientists were required to have a D-index of at least 30.
- Additionally, the majority of their tier publications needed to be in the Engineering and Technology domain.
- Awards and notable achievements in the field were also considered to support the evaluation process.
The D-index threshold is strategically set in increments of 10, calibrated according to the estimated total number of scholars within each discipline, to ensure that the top 1% of leading researchers in Engineering and Technology are represented. Further, the ranking methodology mandates that a scientist’s general H-index and their D-index should not diverge by more than 30%, maintaining discipline-specific relevance in the measurements.
Verification and Cross-Validation Processes
Recognizing that raw bibliometric data alone cannot fully encapsulate a researcher’s scholarly contributions, the Research.com team implemented meticulous manual verification procedures. Every scientist profile was carefully reviewed and cross-validated against publications listed in a broad array of authoritative and trustworthy sources.
While not directly influencing the ranking position, metrics such as the number of papers published in prominent journals and conference proceedings are acknowledged as valuable secondary indicators of a scientist’s research impact and standing within the Engineering and Technology community.
The final ranking positions are rooted in the D-index values derived from data sourced from OpenAlex and CrossRef, which remain the most prominent and reputable databases providing transparent and scholarly citation information available to the global research community.
