Positions in the ranking are determined by aggregating the Discipline H-index (D-index) scores of all ranking scholars affiliated with an institution, with a primary research focus in Computer Science. The D-index uniquely captures disciplinary impact by incorporating exclusively publications and citation data relevant to the specific discipline under evaluation, ensuring precision in measuring expertise within Computer Science.
Scope of Research and Scientist Selection Criteria
The ranking methodology entailed examination of 279,971 scientist profiles aggregated from a diverse array of bibliometric data sources. From this extensive dataset, 41,916 scientists specializing in Computer Science were analyzed in detail. To qualify for inclusion, each scientist was required to meet a minimum D-index threshold of 30, with a majority of their tier publications situated in the Computer Science domain. In addition to bibliometric achievements, scientists' awards and notable accomplishments within their discipline were integrated into the assessment framework.
The D-index threshold for top researchers is dynamically adjusted in increments of 10 relative to the estimated total number of scholars per discipline, ensuring representation of the top 1% of leading experts. Additionally, a proximity criterion mandates that the disparity between a scientist’s general H-index and their D-index remains within 30%, affirming disciplinary focus. Recognition of a scientist’s awards and achievements further complements the evaluation, maintaining a comprehensive measure of research excellence.
Verification and Data Integrity Measures
Recognizing that raw bibliometric data alone cannot fully encapsulate the output and influence of individual scholars, the ranking process incorporates rigorous manual verification of scientist profiles. This includes cross-correlation of publication records against a broad spectrum of trustworthy and authoritative sources, reinforcing the accuracy and authenticity of the data utilized.
While the quantity of papers published in high-impact journals and conference proceedings is not directly factored into the calculation of ranking positions, it serves as an important ancillary indicator of a scientist’s research footprint within Computer Science.
Institutional rankings are based on researchers’ H-index scores as extracted and verified from OpenAlex and CrossRef—two of the most prominent and widely respected bibliometric databases accessible to the global research community.
