Data Sources and Ranking Metrics
The 5th edition of the Research.com Best Engineering and Technology Scientists in Korea Ranking is primarily grounded in comprehensive bibliometric data sourced from OpenAlex and CrossRef, complemented by multiple additional authoritative datasets. On January 12, 2026, an extensive collection of citation-based metrics was undertaken to capture the most current and relevant research outputs. A scientist’s position within this ranking is determined exclusively by their Discipline H-index, or D-index, which reflects citation impact solely within the examined discipline of Engineering and Technology. This metric ensures that disciplinary focus is rigorously maintained when assessing scholarly influence.
Scope of Research and Eligibility Criteria
The ranking encompasses a broad base of 279,971 scientist profiles identified across various bibliometric platforms and disciplines globally, with a specified focus on 260 scientists who specialize in Engineering and Technology. To qualify for inclusion, researchers must exhibit a D-index of at least 30, with the majority of their tier publications situated directly within the Engineering and Technology domain. Furthermore, distinguished awards and achievements within the field are also considered as part of the evaluation criteria.
The threshold for the D-index is strategically calibrated in increments of 10, relative to the estimated total number of scholars in each discipline, effectively ensuring the representation of the top 1% of leading researchers. Additionally, to ensure disciplinary relevance and avoid inflated interdisciplinary metrics, a scientist’s D-index must remain within 30% proximity or less of their general H-index.
Verification and Validation Procedures
Recognizing that raw bibliometric data cannot serve as an absolute measure of scholarly output, the Research.com team undertakes a meticulous manual verification of all scientist profiles. This manual curation includes cross-correlation against publications indexed in multiple reputable sources to ascertain accuracy and validity.
Although not directly influencing the ranking position, the volume of publications appearing in prominent journals and conference proceedings serves as a valuable secondary indicator of a scientist’s substantive contribution to their specialized research field. The primary ranking metric remains the D-index, which relies on data consolidated from the leading bibliometric databases OpenAlex and CrossRef, known for their rigor and widespread acceptance in the scientific research community.
