Data Sources and Metrics
The 5th edition of the Research.com Best Engineering and Technology Scientists in Netherlands Ranking is primarily based on bibliometric data aggregated from leading databases, notably OpenAlex and CrossRef, alongside multiple other reputable data sources. The citation-based metrics underlying the ranking were compiled through rigorous data collection processes on January 12, 2026. A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that exclusively accounts for publications and citation counts within the scientist’s specific discipline, ensuring a focused and discipline-relevant evaluation of research impact.
Scope of Research Considered
The ranking encompasses a comprehensive examination of 279,971 scientist profiles identified across a diverse array of bibliometric data resources, representing all academic disciplines. Within this extensive dataset, 181 scientists specializing in Engineering and Technology were specifically analyzed. To qualify for inclusion in the ranking, a researcher must have a D-index of at least 30, with a majority of their tier publications situated within the Engineering and Technology domain. Additionally, a scientist’s awards and professional achievements relevant to this discipline were considered as supplementary qualitative factors.
The threshold for the D-index was calibrated in increments of 10 according to the estimated total number of scientists in each discipline. This methodology ensures that the top 1% of leading researchers in any given field are integrated into the ranking. Furthermore, there is a requirement that the proximity between a scientist’s general H-index and their discipline-specific D-index does not exceed 30%, reinforcing the discipline focus and coherence of the metric used.
Verification and Validation Practices
The research team behind this ranking acknowledges that raw bibliometric data alone are not sufficient to fully evaluate scholarly output. Therefore, all scientist profiles included in this ranking underwent manual verification and were cross-referenced against publications indexed by a broad spectrum of credible sources. While the quantity of papers published in prominent journals and conference proceedings is not a direct factor influencing a researcher’s position, it remains an important secondary indicator of their contribution to the field of Engineering and Technology.
The ranking positions are ultimately derived from D-index values calculated using data from OpenAlex and CrossRef, two of the most prominent and widely recognized bibliometric databases trusted by the global research community.
