All bibliometric data used to derive the citation-based metrics in this ranking were collected on January 12, 2026. The researchers’ positions in the ranking are determined by their Discipline H-index (D-index), a specialized bibliometric indicator that considers only publications and citations within the specific discipline under examination—Computer Science in this case. This approach ensures that the evaluation accurately reflects scholarly influence in the relevant academic field.
Scope of Research and Selection Criteria
In total, 279,971 scientist profiles across all disciplines, identified from a variety of bibliometric data sources, were examined. From this extensive pool, 38 scientists specializing in Computer Science in Poland were specifically evaluated for inclusion in the ranking.
To qualify for the ranking, a scientist was required to meet the following criteria:
- Possess a D-index of at least 30 within the domain of Computer Science.
- Have a majority of their tier publications classified within the Computer Science discipline.
- Demonstrate notable awards and achievements relevant to Computer Science.
The threshold for the D-index is adapted dynamically, increasing in increments of 10 based on the estimated total number of scholars in each discipline. This methodology ensures that the top 1% of leading scholars are consistently incorporated into the ranking. Furthermore, to guarantee disciplinary alignment, a candidate’s general H-index and their discipline-specific D-index must not differ by more than 30%.
Additional Verification and Validation Practices
The creators of this ranking recognize that raw bibliometric data alone cannot serve as an absolute measure for evaluating scholarly output. Accordingly, every scientist profile included was manually verified and cross-referenced against publications indexed in a wide array of credible and trusted sources. This careful validation process enhances the reliability and credibility of the ranking.
While the number of publications in prestigious journals and conference proceedings does not directly influence the ranking position, it serves as a valuable secondary indicator of a researcher’s contribution to Computer Science.
It is important to emphasize that the ranking position itself is established exclusively based on each researcher's D-index, calculated from data collected via OpenAlex and CrossRef. These platforms remain among the most prominent and respected bibliometric databases available to the scientific community globally.
