Data Sources and Metrics
The 5th edition of the Research.com Best Engineering and Technology Scientists in Norway Ranking is primarily based on comprehensive bibliometric data aggregated from OpenAlex and CrossRef, supplemented by multiple other authoritative data sources. The bibliometric data utilized to devise the citation-based metrics for the ranking was collected on January 12, 2026. Each scientist's position in the 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. This ensures an accurate representation of a researcher's impact specifically within their field of expertise.
Scope of Research and Qualification Criteria
The compilation of this ranking involved an extensive examination of 279,971 scientist profiles identified through a variety of bibliometric sources across all disciplines. Specifically within Engineering and Technology, 55 scientists were carefully reviewed. To qualify for inclusion in the ranking, a scientist’s D-index had to be at least 30, with the majority of their tiered publications falling within the Engineering and Technology domain. Additionally, professional awards and notable achievements pertinent to Engineering and Technology were considered to provide a holistic assessment of a researcher’s contribution.
The D-index threshold for considering top researchers is dynamically adjusted in increments of 10 based on the total estimated number of scholars in each discipline. This approach also guarantees the inclusion of the top 1% of leading scholars within the ranking. Furthermore, a close alignment is maintained between a scientist’s general H-index and their D-index, enforcing a proximity threshold of 30% or less to ensure discipline-specific impact is accurately reflected.
Verification and Quality Assurance
Recognizing that raw bibliometric data alone is insufficient for absolute evaluation of scholarly output, all scientist profiles included in the ranking underwent manual verification. Profiles were meticulously cross-correlated against publications indexed in a broad range of trustworthy sources to ensure accuracy and validity.
Although the number of publications in prominent journals and conference proceedings is not a factor in determining position within the Research.com ranking, it serves as a valuable secondary signal indicating the extent of a scientist’s research contributions in their specific area. The final ranking positions are established using each researcher's D-index derived from OpenAlex and CrossRef data, the most prominent and respected bibliometric databases available to the scholarly community.
