Bibliometric data used to create citation-based metrics for this ranking were collected on January 12, 2026. The positioning of each scientist within the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only papers and citation metrics pertinent to the specific examined discipline—Computer Science in this case. This approach ensures that a researcher’s impact is accurately reflected within their particular field of expertise.
Scope of Research and Qualification Criteria
The ranking’s foundation is extensive and multidisciplinary, having examined a total of 279,971 scientist profiles derived from a variety of bibliometric data sources across all scientific disciplines. Specifically within Computer Science, 519 scientist profiles were carefully analyzed.
To qualify for inclusion in the Computer Science ranking, a researcher must have a D-index of at least 30, with the majority of their top-tier publications falling within the area of Computer Science. In addition, a scientist’s awards and significant achievements in the field were also considered as factors enhancing their standing.
The D-index threshold used to identify leading researchers is set in increments of 10, calibrated according to the estimated population size of scholars in each discipline. This methodology guarantees that the top 1% of scholars within each field are incorporated in the ranking. Furthermore, to ensure disciplinary focus, there is a requirement that the difference between a scientist’s general H-index and their D-index should remain at 30% or less, confirming consistency between their overall and discipline-specific impact.
Additional Verification Practices
At Research.com, we recognize that raw bibliometric data alone cannot serve as an absolute measure of a scholar’s academic contributions. As such, all scientist profiles included in this ranking have undergone manual verification. This process included cross-referencing each researcher’s publications against authoritative and trustworthy sources to verify accuracy and relevance.
While the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it is regarded as a valuable secondary indicator of their contribution to computer science research. The primary metric driving the ranking remains the D-index, calculated using data from OpenAlex and CrossRef—two of the most prominent and widely respected bibliometric databases accessible to the research community.
