Institutional positions in the ranking are determined by aggregating the D-indexes (Discipline H-index) of all eligible scholars whose main publication domain is Computer Science and who are affiliated with the institution. The D-index computation strictly considers publications and citation data pertinent to the Computer Science discipline, ensuring a focused evaluation of disciplinary impact.
Scope of Research and Ranking Criteria
To ensure the integrity and scope of the ranking, an initial dataset of 279,971 scientist profiles was examined, spanning various distinct disciplines. Out of these, 40,471 scientists linked primarily to Computer Science were selected for in-depth analysis.
Researchers were required to meet a minimum D-index threshold of 30, with the majority of their significant publications situated firmly in Computer Science. An incremental threshold system—rising by steps of 10 based on the total scholarly population within each discipline—guarantees representation of the top 1% of scholars for every field.
Additional selection criteria include:
- The scientist’s D-index in Computer Science must stay within 30% of their overall H-index, establishing the primacy of Computer Science within their publication record.
- Awards and notable achievements in Computer Science also play a crucial role in a scholar’s inclusion and assessment.
This meticulous approach underpins the credibility and depth of the ranking.
Verification and Quality Assurance
Recognising that bibliometric data alone present an incomplete picture, the Research.com team has subjected all scientist profiles to careful manual verification. Each entry was cross-correlated against publications listed in multiple reliable and authoritative sources, ensuring robust data accuracy.
While the volume of papers in high-impact journals and proceedings does not directly influence ranking positions, it provides a valuable qualitative signal of a scientist’s contribution to their field.
Crucially, positions in the ranking are informed by the individual researcher’s H-index as determined by exhaustive analysis through OpenAlex and CrossRef—preeminent authorities in bibliometric indexing for the scientific community.
