The bibliometric data employed for devising the citation-based metrics used in this ranking were collected on January 12, 2026. Each scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only papers and citations specific to the examined discipline—in this case, Computer Science. This approach ensures discipline-specific relevance, enhancing the precision of the evaluation.
Scope of Research and Eligibility Criteria
This edition involved an examination of 279,971 scientist profiles aggregated from various bibliometric data sources across all scientific disciplines. Within this comprehensive dataset, 130 researchers specializing in Computer Science based in Belgium were analyzed in detail.
To qualify for inclusion in the ranking, a scientist’s D-index had to meet a minimum threshold of 30. Furthermore, a majority of the researcher’s tier publications needed to be within the domain of Computer Science, guaranteeing focused expertise in the relevant area. Awards and achievements in Computer Science were also factored into the assessment to provide a more complete representation of the researcher’s impact.
The D-index threshold is adaptively set in increments of 10, reflecting the total estimated number of scholars within each discipline. This methodology ensures that the ranking consistently captures approximately the top 1% of leading scholars. Additionally, a proximity criterion mandates that the disparity between a scientist’s general H-index and their discipline-specific D-index is no greater than 30%, which underscores the researcher’s consistent impact within their focused area.
Additional Verification Practices
Recognizing the inherent limitations of raw bibliometric data as a singular evaluative tool, the research team undertook manual verification of all scientist profiles. This process involved cross-correlation of publications against a broad spectrum of trustworthy sources to enhance the accuracy and integrity of the ranking.
While the quantity of papers published in prominent journals and conference proceedings is not a direct factor determining rank position, it serves as an important secondary signal reflecting a scientist’s contribution and research activity within their discipline.
The ranking positions are ultimately established using each researcher’s D-index derived from the most prominent bibliometric databases available—OpenAlex and CrossRef—both widely recognized by the research community for their rigorous curation and expansive coverage.
