Each institution's position in the ranking is determined by aggregating the D-indexes (Discipline H-index) of all affiliated scholars whose principal publication focus is in Engineering and Technology. The D-index is a metric that exclusively accounts for publications and citation data within the examined discipline, thus ensuring precise representation of scholarly impact within Engineering and Technology.
Scope of Research and Evaluation Criteria
The ranking is underpinned by a comprehensive evaluation of 279,971 scientist profiles sourced from a variety of bibliometric datasets. Among these, 50,429 scientists specializing directly in Engineering and Technology were analyzed in depth. To maintain the highest standards of selectivity and relevance, a qualifying D-index threshold of 30 was implemented; in addition, the majority of a scientist's significant publications had to fall within the sphere of Engineering and Technology.
The assessment protocol also took into account scientist’s awards and notable achievements in the domain of Engineering and Technology. The D-index threshold for identifying top researchers is adjusted in increments of 10, tailored to the estimated volume of scholars in each discipline, and ensuring that the leading 1% of scholars are incorporated into the list. Furthermore, to guarantee discipline specificity, eligibility required that a scientist’s general H-index should not exceed their D-index by more than 30%.
Scientist’s leadership, awards, and achievements in their field of study were also considered as supplementary factors in the evaluation.
Rigorous Verification Practices
The Research.com team fully recognizes that raw bibliometric data, while immensely valuable, should not be used as the sole instrument for evaluating scholarly output. In recognition of this, every scientist profile selected through the automated processes was meticulously manually verified and cross-referenced across an array of trustworthy publication sources to ensure both accuracy and credibility.
While not directly factoring into an individual researcher’s ranking position, the volume of papers published in acknowledged leading journals and high-impact conference proceedings is noted as a valuable secondary indicator of scholarly contribution within specific research areas.
Ranking positions are derived based on the H-index and D-index of each researcher, with the relevant metrics being collated chiefly from OpenAlex and CrossRef, databases renowned for their comprehensive and authoritative coverage of research outputs.
