Data Sources and Bibliometric Basis of the Ranking
The 5th edition of the Research.com Best Engineering and Technology Scientists in Vietnam Ranking is constructed primarily using bibliometric data aggregated from OpenAlex, CrossRef, as well as multiple additional reputable data sources. These platforms provide comprehensive coverage of scholarly publications and citation information essential for a robust and transparent ranking process. The bibliometric data underpinning the citation-based metrics employed in this ranking were collected on January 12, 2026, ensuring the most recent and accurate information is utilized for evaluation.
A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that specifically accounts for papers and citation metrics within the examined discipline of Engineering and Technology. This metric allows for a focused assessment of a researcher’s impact and relevance within their specialized field.
Scope of Research and Qualification Criteria
The ranking process examined a comprehensive dataset encompassing 279,971 scientist profiles identified from various bibliometric data sources across all disciplines. Within this broad spectrum, 9 scientists were specifically analyzed under the Engineering and Technology domain.
- To qualify for inclusion in the ranking, a scientist’s D-index was required to be at least 30.
- A majority of the scientist’s tier publications needed to be situated within the field of Engineering and Technology, ensuring domain-specific relevance.
- Awards and notable achievements within the field were also considered as supplementary criteria.
The threshold for the D-index is set strategically as increments of 10, relative to the estimated total number of scholars in each discipline. This approach guarantees that the top 1% of leading scholars in Engineering and Technology are incorporated into the list. Furthermore, to maintain consistency and discipline alignment, the difference between a scientist’s general H-index and their D-index is kept within a proximity of 30% or less.
Additional Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot fully capture the quality and impact of scholarly output, the Research.com team has conducted meticulous manual verification of all scientist profiles included in the ranking. This includes cross-correlation of publication records against a wide array of trustworthy sources to validate authenticity and relevance.
Although the number of papers published in prominent journals and conference proceedings is not directly factored into the position within the ranking, it serves as a valuable secondary indicator of a scientist’s contributions within the specific domain of Engineering and Technology.
The ranking position is fundamentally established using each researcher’s D-index derived from data gathered through OpenAlex and CrossRef—the most prominent and widely acknowledged bibliometric databases available to the research community.
