Data Sources and Bibliometric Collection
The 12th edition of the Research.com Best Computer Science Scientists in Korea Ranking is primarily based on comprehensive bibliometric data collected from OpenAlex and CrossRef, complemented by multiple other reputable sources. These databases are among the most prominent and widely recognized repositories of academic publication and citation metadata, providing a robust foundation for the citation-based metrics used in this ranking. The bibliometric data utilized for calculating these metrics were collected on January 12, 2026, ensuring the analysis reflects the most recent scholarly output.
A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined measure that assesses citation impact strictly within the boundaries of an examined discipline. This metric considers only publications and citation counts relevant to Computer Science, providing a discipline-specific evaluation of scholarly influence.
Scope of Research and Eligibility Criteria
The ranking process examined a total of 279,971 scientist profiles sourced from a diverse array of bibliometric repositories spanning all disciplines. Within this extensive dataset, 188 scientists specializing in Computer Science were identified and assessed.
To qualify for inclusion in the Computer Science ranking, candidates were required to meet the following criteria:
- A minimum D-index of 30, ensuring a baseline of disciplinary impact.
- A majority of their tier publications had to be directly related to Computer Science.
- Their awards and notable achievements within the field of Computer Science were also taken into consideration as supplementary evaluation factors.
The threshold for the D-index is dynamically set in increments of 10 to reflect the estimated total number of scholars in each discipline while guaranteeing the incorporation of the top 1% of leading experts. Furthermore, a proximity check was applied to confirm that the D-index and the general H-index of a scientist do not differ by more than 30%, ensuring consistency between their overall and discipline-specific impact.
Additional Verification Practices
We recognize that raw bibliometric data alone cannot fully capture the qualitative nuances of scholarly output. Therefore, all scientist profiles included in the ranking underwent manual verification by experts who cross-referenced publication records across a wide range of trustworthy academic sources. This meticulous process ensures the accuracy and integrity of each profile.
Although the number of papers published in high-impact journals and renowned conference proceedings is not a direct factor influencing a researcher’s position in the Research.com ranking, it remains a valuable secondary indicator of a scientist’s contribution and standing in the field.
The ranking positions are ultimately established using each researcher’s D-index, computed from data drawn chiefly from OpenAlex and CrossRef. These databases represent the most comprehensive and credible bibliometric data sources available to the research community today.
