The ranking methodology centers around the D-index (Discipline H-index), a refined metric that evaluates a researcher's impact within a specific discipline by including only publications and citation metrics pertinent to that domain. This discipline-specific approach provides a more precise reflection of a scientist’s contributions to Engineering and Technology than traditional overall H-index measures.
Scope of Research and Ranking Criteria
This edition examines a broad spectrum of profiles, initially considering 279,971 scientist profiles identified from a diverse set of bibliometric data sources spanning all academic disciplines. Of these, 59 researchers specializing in Engineering and Technology, with a significant footprint within Saudi Arabia, were evaluated in detail.
To qualify for inclusion in the Engineering and Technology ranking, a scientist must have a D-index of at least 30. Additionally, the majority of their tier publications must pertain specifically to the field of Engineering and Technology. The researchers’ awards and notable achievements within this domain were also incorporated as qualitative factors to ensure recognition of excellence beyond raw citation counts.
It is important to note that the D-index threshold is dynamically set in increments of 10, scaled according to the estimated total number of scholars in each discipline. This approach guarantees that the ranking consistently covers the top 1% of leading experts within the field. To ensure thematic focus and metric integrity, a proximity threshold of 30% or less between a scientist's general H-index and their D-index is maintained.
Verification and Validation Practices
The Research.com team acknowledges the limitations of raw bibliometric data as an absolute evaluative measure of scholarly output. Consequently, all scientist profiles included in the ranking underwent exhaustive manual verification. Each profile was cross-correlated against publications indexed in a wide variety of trustworthy and well-established sources to confirm accuracy and relevance.
While the number of publications in prominent journals and leading conference proceedings is not directly factored into the ranking position, such considerations serve as valuable secondary indicators of a scientist’s impact and research contribution within their specialization.
The final position in the ranking is determined based on each researcher's D-index, rigorously computed using citation and publication data primarily obtained from OpenAlex and CrossRef.
