Data Sources and Bibliometric Basis of the Ranking
The 12th edition of the Research.com Best Computer Science Scientists in Kazakhstan Ranking was primarily developed utilizing data from OpenAlex and CrossRef, supplemented by multiple other reputable bibliometric data sources. These comprehensive data repositories provide extensive coverage of scholarly publications and citations across disciplines, ensuring a robust foundation for the ranking metrics. The bibliometric information used to calculate citation-based metrics was collected on January 12, 2026, guaranteeing the most current and reliable dataset available at the time of compilation.
A scientist’s position within the ranking is determined based on their D-index (Discipline H-index), a specialized metric that considers only those publications and citations directly relevant to the examined discipline—in this case, Computer Science. This discipline-specific approach enables a more precise assessment of a researcher’s impact within their field.
Scope of Research Considered
To establish a comprehensive overview, a total of 279,971 scientist profiles drawn from diverse bibliometric data sources across all disciplines were initially examined. Specifically within Computer Science, 1,000 scientists were identified and screened for inclusion. Qualification for the ranking required that a scientist’s D-index be at least 30, and that the majority of their tier publications were concentrated in the area of Computer Science.
In addition to bibliometric indicators, scientists’ awards and achievements within the field of Computer Science were also considered as qualitative factors contributing to their evaluation. The threshold for the D-index is calibrated in increments of 10 in accordance with the estimated total number of scholars per discipline, ensuring the inclusion of the top 1% of leading experts within the ranking. Furthermore, to guarantee subject-specific relevance, a criterion was established requiring a proximity of 30% or less between a scientist’s general H-index and their D-index.
Additional Verification Practices
The researchers and analysts behind this ranking recognize that raw bibliometric data alone cannot serve as an absolute measure of scholarly impact. Accordingly, each scientist profile underwent meticulous manual verification and cross-correlation against publications available through a wide array of trustworthy academic sources. While the number of papers published in prominent journals and conference proceedings does not directly influence the ranking position, it constitutes a valuable secondary signal—offering additional insight into a scientist’s contributions within their specific domain.
The ranking positions are ultimately established by leveraging each researcher’s D-index as calculated using data meticulously gathered from OpenAlex and CrossRef, two of the most prominent and recognized bibliometric databases accessible to the global research community.
