Institutional positions within the ranking are determined by aggregating the D-indexes (Discipline H-indexes) of all ranking scholars affiliated with each institution, provided their primary publication area is in Engineering and Technology. The D-index metric focuses exclusively on publications and citation data pertinent to the specific discipline under consideration, ensuring a high degree of relevance and domain fidelity.
Scope of Research
The extensive scope of the ranking is anchored in the examination of 279,971 scientist profiles sourced from an array of bibliometric databases. Out of these, 50,429 profiles were identified and analyzed as belonging specifically to the Engineering and Technology sector. To ensure only the most impactful scientists are included, a qualifying D-index threshold of 30 was set, with the additional requirement that the majority of a scientist's most significant publications reside within Engineering and Technology.
The process further incorporates consideration of notable awards and achievements within the discipline. The threshold for the D-index is strategically set in increments of 10, dependent on the total number of scholars estimated for each discipline. This approach guarantees that the upper echelon—top 1%—of leading scholars is always represented. For inclusion, a proximity of 30% or less between a scientist’s general H-index and their D-index is required, cementing the scholar’s established focus within the discipline. Recognitions and honors achieved in the field are also accounted for, reflecting a broader picture of scholarly impact beyond citations alone.
Verification Practices and Data Reliability
Acknowledging that raw bibliometric data should not be seen as an absolute measure of scholarly output, the ranking procedure includes comprehensive manual verification of all scientist profiles. This includes cross-referencing each profile’s publications against a multitude of reliable sources to eliminate discrepancies and enhance accuracy.
Although the absolute number of papers published in top-tier journals and conference proceedings does not directly influence a scientist’s position in the Research.com ranking, it serves as a valuable secondary indicator of research contribution, and is considered in the broader assessment. Ranking position is firmly established using each researcher’s H-index, as gathered from OpenAlex and CrossRef—two of the most authoritative and widely recognized bibliometric databases globally.
