Data Sources and Bibliometric Foundations
The 5th edition of the Research.com Best Engineering and Technology Scientists in Kazakhstan Ranking is primarily constructed upon bibliometric data sourced from OpenAlex and CrossRef, two of the most prominent and widely recognized databases within the global research community. These databases were complemented by multiple other reputable bibliometric sources to ensure a broad and accurate data pool. The citation-based metrics that underpin the ranking were collected on January 12, 2026, providing a current and comprehensive snapshot of scholarly performance.
A scientist’s position within the ranking is determined through their Discipline H-index (D-index), a refined metric that accounts exclusively for publications and citations within the examined discipline—Engineering and Technology in this case. This approach ensures that the ranking reflects a researcher’s specific impact and productivity relevant to the field.
Scope and Criteria of Research Considered
The ranking draws from an extensive examination of 279,971 scientist profiles identified across a wide range of bibliometric data sources, spanning all disciplines. Within this large dataset, 7 scientists specializing in Engineering and Technology were carefully evaluated for inclusion. To qualify for the ranking, a researcher’s D-index must be at least 30, and the majority of their tier publications must focus squarely on Engineering and Technology. Furthermore, consideration was given to scientists’ awards and significant achievements within this field to ensure recognition of qualitative impact alongside quantitative metrics.
For setting the D-index threshold, a dynamic scale was applied: increments of 10 depending on the estimated total number of scholars per discipline. This stratification is designed to guarantee the inclusion of the top 1% of leading scholars in the ranking, consistent across various scales of research communities. Additionally, a proximity criterion was enforced such that there is no greater than a 30% difference between a scientist’s general H-index and their D-index, maintaining relevance of discipline-specific impact in relation to overall scholarly influence.
Additional Verification and Validation Practices
The Research.com team acknowledges that raw bibliometric data alone can never serve as an absolute measure of scholarly output or impact. Accordingly, every scientist profile included in the ranking was manually verified and rigorously cross-correlated against publications indexed in a diverse array of trustworthy sources. This meticulous verification process enhances the accuracy and credibility of the ranking.
While not a direct factor influencing ranking positions, the number of papers published in prominent journals and conference proceedings is also noted as an important secondary signal of a scientist’s contribution to their specific field of study. The prominent reliance on OpenAlex and CrossRef data ensures the ranking’s foundation is based on the most reliable and comprehensive bibliometric databases currently accessible to the research community.
