A researcher’s position in this ranking is determined exclusively by the D-index (Discipline H-index), a refined measure that accounts only for papers and citations relevant to the specific discipline under examination—Computer Science in this case. This discipline-specific focus ensures that the ranking accurately reflects excellence and influence within the targeted research area.
Scope of Research and Inclusion Criteria
To develop a robust and representative ranking, we examined a total of 279,971 scientist profiles aggregated from diverse bibliometric datasets spanning all disciplines. Specifically, 32 scientists from the Computer Science discipline based in the Czech Republic were identified and evaluated in detail.
In order to qualify for inclusion in the ranking, candidates were required to demonstrate a D-index of at least 30, with the majority of their tier publications occurring within the field of Computer Science. Additionally, scientists' awards and notable achievements within the discipline were considered to further reflect their impact and recognition in the field.
The threshold for the D-index is adaptively set in increments of 10 based on the estimated total number of scholars in each discipline, with the express goal of incorporating approximately the top 1% of leading researchers into the list. To maintain disciplinary relevance, we also require that the difference between a scientist's overall general H-index and their D-index does not exceed 30%.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot fully capture the complexities of scholarly output, the researchers behind this ranking conducted thorough manual verifications of all scientist profiles. Each profile was cross-correlated against publications from a broad spectrum of trustworthy and authoritative sources to validate accuracy and reduce errors stemming from data aggregation or misattribution.
Although not factored directly into the final ranking position, the number of papers published in leading journals and conference proceedings serves as a valuable secondary indicator of a scientist’s contribution to the field. This additional context reinforces the credibility and depth of the portrayals of excellence.
It is important to note that the ranking is fundamentally based on each researcher’s D-index, calculated using data exclusively from OpenAlex and CrossRef—acknowledged as the most comprehensive and reliable bibliometric resources available to the global research community.
