An institution’s position in the ranking is determined by the sum of the D-indexes (Discipline H-index) of all scholars affiliated with that institution whose primary publication area is in Engineering and Technology. The D-index is a discipline-sensitive metric that considers only publications and citation data specific to the examined field, thereby providing an accurate measure of a scholar's impact in Engineering and Technology.
Scope of Research and Scholar Selection Criteria
The ranking’s foundation lies in an extensive analysis of 279,971 scientist profiles sourced from various bibliometric datasets. From this broad pool, a focused cohort of 50,429 scientists specializing in Engineering and Technology was thoroughly examined.
To ensure only highly impactful researchers are considered, a qualifying D-index threshold of 30 was set, and a majority of each candidate’s publications needed to be in Engineering and Technology. Furthermore, a scientist’s awards and achievements in the field played a significant role in their qualification.
The D-index threshold for top researchers is incrementally adjusted in steps of 10, depending on the estimated total number of scholars in each discipline, ensuring that at least the leading 1% of scholars are represented. Additionally, to maintain discipline relevance, the proximity between a scientist’s general H-index and their D-index must not exceed 30%. This guarantees that only those with a predominant focus on Engineering and Technology are included.
In summary, the criteria for scholar inclusion balance rigorous bibliometric thresholds with an acknowledgment of recognized achievements and discipline-specific focus.
Verification and Quality Assurance Practices
The integrity and reliability of the Research.com ranking are reinforced through comprehensive verification processes. Recognizing the inherent limitations of bibliometric data, the Research.com team conducted manual checks of all scientist profiles to ensure accurate affiliations and proper discipline classification. Each profile was cross-referenced against publications in a wide array of trusted bibliographic sources.
While not a formal determinant in the ranking, the number of papers published in leading journals and conference proceedings serves as an additional indicator of a scientist’s contribution to their field. The principal ranking metric remains the researcher’s H-index, as sourced from OpenAlex and CrossRef — two of the most respected bibliometric databases globally.
