The bibliometric data used for deriving the citation-based metrics were collected on January 12, 2026. This ensured that the ranking reflects the most current research contributions and impact as measured through citations.
A scientist’s position within the ranking is determined by their D-index (Discipline H-index), which is a metric focused exclusively on publications and citation metrics relevant to the examined discipline—in this case, Computer Science. This approach ensures discipline-specific evaluation, accurately reflecting expertise and influence within the field.
Scope of Research and Qualification Criteria
In creating this ranking, 279,971 scientist profiles were examined across all disciplines, identified through a variety of bibliometric data sources. Specifically for Computer Science, profiles of 11,000 scientists were analyzed to determine their standing.
To qualify for inclusion in the Computer Science ranking, a researcher’s D-index had to be at least 30, and the majority of their tier publications needed to belong to the Computer Science discipline. Additionally, scientists’ awards and notable achievements within the field were taken into consideration as supplementary indicators of their contribution.
The D-index threshold for recognizing top researchers is established in increments of 10, calibrated according to the estimated total number of scholars within each discipline. This methodology guarantees that the top 1% of leading scientists in the field are incorporated into the list. Furthermore, the proximity between a scientist’s general H-index and their D-index is maintained at 30% or less, ensuring that their core disciplinary impact is well represented.
Additional Verification Practices
The research team behind this ranking understands that raw bibliometric data, while invaluable, cannot serve as an absolute measure of scholarly output. Accordingly, all scientist profiles included have undergone meticulous manual verification. Profiles were cross-correlated against publications listed in a wide array of trustworthy, peer-reviewed sources to confirm accuracy and authenticity.
Although not a direct factor influencing ranking position, the number of papers published in prominent journals and high-impact conference proceedings is considered a valuable secondary signal of a scientist’s scholarly contribution to their specific area of science.
The ranking positions are ultimately established using each researcher’s D-index, calculated from data gathered through OpenAlex and CrossRef—two of the most prominent and well-regarded bibliometric databases available to the academic community.
