Data Sources and Metrics
The 5th edition of the Research.com Best Engineering and Technology Scientists in Vietnam Ranking was developed using a comprehensive aggregation of bibliometric data primarily sourced from OpenAlex and CrossRef, complemented by multiple other reputable data repositories. The citation-based metrics underpinning this ranking were meticulously collected on January 12, 2026. A scientist’s position within the ranking is determined based on their D-index (Discipline H-index), a refined metric that considers only papers and citations directly relevant to the examined discipline, thereby ensuring a precise reflection of research impact within Engineering and Technology.
Scope of Research and Eligibility Criteria
The ranking encompasses an extensive examination of 279,971 scientist profiles identified across diverse bibliometric databases and research repositories, spanning all academic disciplines. Within this expansive dataset, nine scientists specializing in Engineering and Technology in Vietnam were rigorously evaluated. To qualify for inclusion, a researcher must have attained a minimum D-index of 30, with a majority of their high-tier publications concentrated within the Engineering and Technology domain. Additionally, awards and notable achievements within the field were factored into the selection process.
The threshold for the D-index is dynamically adjusted in increments of 10 in correlation with the estimated total number of scholars per discipline. This approach ensures that the top 1% of leading researchers in each field are effectively captured in the ranking. Furthermore, the methodology requires that the proximity between a scientist’s overall H-index and their discipline-specific D-index should not exceed 30%, reinforcing the significance of focused disciplinary impact.
Verification and Validation Practices
Recognizing the inherent limitations of raw bibliometric data as the sole evaluative tool, the Research.com team undertook rigorous manual verification processes for all scientist profiles. Each profile was carefully cross-referenced against publications from a broad spectrum of trustworthy and authoritative sources to ensure accuracy and authenticity. Although the quantity of publications appearing in prominent journals and conference proceedings does not directly influence ranking positions, it serves as a valuable secondary indicator of a scientist’s substantive contributions within their research area.
The final positioning in the ranking is based on each researcher’s D-index, calculated exclusively using information retrieved from OpenAlex and CrossRef—two of the most acclaimed and widely utilized bibliometric databases available to the scientific community.
