An institution's position in the ranking is determined by the sum of D-indexes (Discipline H-indexes) of all affiliated scholars whose primary publication domain is Engineering and Technology. The D-index metric focuses exclusively on discipline-specific publications and citations, ensuring that an institution’s performance in Engineering and Technology research is precisely evaluated.
Scope and Criteria of the Research
To ensure the integrity and relevance of the ranking, a comprehensive review of 279,971 scientist profiles across a variety of bibliometric data sources was conducted. Of these, 50,429 scientists specializing in Engineering and Technology were selected for in-depth analysis.
The qualification criteria required each scientist to have a minimum D-index of 30, with the bulk of their principal publications falling within Engineering and Technology. Additionally, awards and tangible achievements in the field further contributed to a scholar's consideration.
The threshold for top researchers is refined through increments of 10 for the D-index, calibrated according to the discipline’s total number of scholars, and guarantees that the top 1% of leading experts are incorporated. An added quality assurance stipulates that the difference between a scientist’s general H-index and their D-index stays within a margin of 30%, further honing the specificity of the list. Notably, recognition of scientists' exceptional awards and achievements in their areas of study is also assessed as part of the overall evaluation.
Verification Practices and Data Integrity
The team behind the ranking recognizes that raw metrics alone cannot encapsulate the full scope of scholarly achievement. Accordingly, each scientist’s profile underwent manual verification and was cross-referenced against a broad array of trustworthy publication sources to validate data reliability.
While the number of articles published in prestigious journals and significant conference proceedings does not directly influence the ranking outcome, it is considered a valuable secondary indicator of a scientist's impact in the field. The final position of each researcher—and by extension, each university—is determined by the H-index data as derived from OpenAlex and CrossRef, currently the most recognized bibliometric databases serving the scholarly community.
