A university’s position in the ranking is determined by the aggregate of D-indexes (Discipline H-index) of all ranking scholars affiliated with the institution whose primary publication area is Engineering and Technology. The D-index is a nuanced metric encompassing exclusively publications and citation data relevant to the analyzed discipline, ensuring that the impact of scholars in Engineering and Technology is accurately represented.
Scope and Criteria of the Research
For this edition, an extensive assessment of 279,971 scientist profiles from diverse bibliometric data sources was undertaken, out of which 50,429 scientists specializing in Engineering and Technology were analyzed. The threshold D-index required for a scientist to qualify for analysis was set at 30, ensuring that only researchers with significant impact were considered. Furthermore, a majority of each scientist’s most impactful publications needed to be within the field of Engineering and Technology.
In addition to bibliometric measures, the awards and achievements of each scientist in Engineering and Technology were also factored into the evaluation process. The D-index threshold for top researchers is incrementally adjusted by 10 points depending on the number of scholars estimated in each discipline, while ensuring inclusion of the top 1% of leading scientists. An additional criterion required that the proximity between a scientist’s general H-index and their D-index not exceed 30%, further attesting to the researcher’s primary focus and recognition within the discipline. Awards and notable contributions in the field continued to play a supportive role in assessment.
Verification and Validation Practices
The team behind the Research.com ranking acknowledges that raw bibliometric data, while powerful, is not an absolute gauge for scholarly achievement. To uphold integrity and credibility, all scientist profiles were subject to manual verification, and their records were cross-checked against a wide array of trustworthy publication sources. While the number of papers published in prominent journals and conference proceedings does not directly influence ranking positions, it offers valuable secondary insight into a scientist’s contribution to their area of expertise.
Ultimately, a researcher’s positioning within the ranking stems from their H-index as detailed by the comprehensive datasets provided by OpenAlex and CrossRef—among the most established bibliometric databases in widespread academic use.
