Data Sources and Citation Metrics
The 5th edition of the Research.com Best Engineering and Technology Scientists in Taiwan Ranking is primarily derived from comprehensive bibliometric data collected from leading scholarly databases, including OpenAlex and CrossRef, supplemented by multiple other authoritative data sources. The citation-based metrics, which form the foundation for the ranking, were compiled on January 12, 2026. A scientist’s standing in the ranking is determined by their D-index (Discipline H-index), a specialized metric that considers only the publications and citation data within the specific discipline under examination, in this case, Engineering and Technology.
Scope of Research and Inclusion Criteria
Our analytical scope encompassed a total of 279,971 scientist profiles across all disciplines, identified through a rigorous aggregation of diverse bibliometric datasets. Within the field of Engineering and Technology, 111 scientists met the threshold for detailed evaluation. To qualify for inclusion, researchers were required to have a minimum D-index of 30, ensuring that only highly impactful contributors were considered. Additionally, the majority of tier-one publications for each candidate had to be within the Engineering and Technology domain. Recognized awards and notable achievements in the field were also factored into the assessment.
The selection process implements a dynamic D-index threshold, increasing in increments of 10 relative to the estimated total number of scientists in each discipline. This approach guarantees that the top 1% of leading scholars are included in the ranking. Furthermore, to maintain disciplinary focus, the disparity between a scientist’s overall H-index and their discipline-specific D-index is restricted to 30% or less, ensuring relevant alignment between general impact and domain-specific contributions.
Verification Practices and Methodology Transparency
Recognizing that raw bibliometric data alone does not fully capture the qualitative impact of scientific contributions, the Research.com team undertakes thorough manual verification of all scientist profiles. This process includes cross-correlation against a broad spectrum of reputable publication sources to confirm accuracy and validity.
While the number of publications in high-impact journals and prominent conference proceedings does not directly influence the ranking position, it serves as a valuable secondary indicator of a scientist’s contribution within their discipline. The primary ranking metric remains the D-index, calculated using curated data from OpenAlex and CrossRef – the two most prominent and trusted bibliometric databases accessible to the global research community.
