A university's position in the ranking is determined by the aggregate D-indexes (Discipline H-index) of all ranking scholars affiliated with the institution, whose chief research area is Engineering and Technology. The D-index strictly counts publications and citations within the specified discipline, ensuring that the ranking reflects subject-specific research excellence.
Scope of Research and Ranking Criteria
To ensure a rigorous evaluation, the ranking process involved the review of 279,971 scientist profiles sourced from a variety of bibliometric data repositories. Of these, 50,429 scientists working in Engineering and Technology were selected and analyzed in depth. Each candidate was required to have a minimum D-index threshold of 30, and the majority of their high-level publications needed to be within Engineering and Technology.
Additional factors considered included the scientist’s awards and achievements specific to the field of Engineering and Technology. The D-index threshold for recognition among top researchers is set in increments of 10, calibrated according to the total number of scholars present in each sub-discipline. This incremental approach guarantees the inclusion of the top 1% of leading scholars within the discipline.
Furthermore, to maintain disciplinary focus, there had to be a proximity of 30% or less between each scientist's general H-index and their D-index. Assessment of achievements, such as field-specific awards, were also incorporated to provide a holistic evaluation.
Verification and Assurance Practices
Understanding the limitations of raw bibliometric data, the Research.com team undertook meticulous manual verification of all scientist profiles. Each profile was cross-referenced and validated against publications from a broad spectrum of trustworthy and authoritative sources.
While the count of publications in leading journals and significant conference proceedings does not directly impact a researcher’s ranking, it is nevertheless acknowledged as an important secondary indicator of impact and contribution to the field. The rank itself is established using every researcher's H-index as provided by OpenAlex and CrossRef, which are globally recognized and extensively used bibliometric databases.
