The 2nd edition of Research.com ranking of the best universities in the arena
of Engineering and Technology relies os data consolidated from
a wide range of data sources including OpenAlex and CrossRef. The bibliometric data for
devising the citation-based metrics were collected on 21-12-2022.
Position in the ranking is based on a sum of D-indexes (Discipline H-index) of all ranking
scientist's affiliated with a given institution. D-index
only includes publications and citation
values for an examined discipline.
The range of our Engineering and Technology research
Research.com’s best universities ranking is a trustworthy lineup of leading researchers from the field of Engineering and Technology , based on a thorough study of 166,880 scientists determined from a variety of bibliometric data sources. For the field of Engineering and Technology, as many as 27940 scholars were examined.
What is D-index inclusion threshold for Engineering and Technology
The D-index threshold for accepting a researcher to be considered is placed at 30 if the majority of of their publications are in the field of Engineering and Technology. The acceptance factors for scientists to be considered into the ranking of top scholars are based on the D-index, ratio of the contributions made within the specific discipline plus the awards and achievements of the researchers. The D-index threshold for including leading scientists is set as an increment of 10 depending on the total number of scientists assessed for each discipline whilst making sure that the top 1% of best scholars are incorporated into the ranking. We estimate a proximity of 30% or less between a scholar’s general H-index and their D-index.
Additional verification methods
As our main mission is to ensure that only genuine researchers are mentioned in the ranking we believe that numbers are never meant to be an absolute tool to quantify the contributions of scholars. For that reason we manually check each profile and cross-correlate it against publications in a wide range of credible sources. Although it’s not a metric impacting a scholar’s position in our ranking, the amount of documents published in major journals and conference proceedings should form a reliable secondary signal of their contribution to research in a given area of science. Position in the ranking is established using each researcher’s D-index according to information compiled from OpenAlex and CrossRef, which are the most prominent and well-established bibliometric databases of this type accessible to the scientific community. A thorough definition of our research procedures can be found on our methodology page.
Our objective is to inspire scientists, entrepreneurs and decision-makers around the world to examine where prominent experts are heading and to offer an opportunity for the whole research community to discover who the leading experts in specific disciplines, in various countries, or even within research institutions are.
