Data Sources for the Research.com Best Computer Science Universities in Brazil Ranking – 11th Edition
The 11th edition of the Research.com Best Computer Science Universities in Brazil Ranking leverages a robust set of bibliometric data sources, with OpenAlex and CrossRef serving as the primary repositories. These platforms provide comprehensive, up-to-date records of publications and citations, enabling a broad and credible assessment of scholarly output. Supplementing these primary sources, data was also gathered from multiple additional reputable bibliometric databases to ensure completeness and accuracy.
For this edition, bibliometric data underpinning the citation-based metrics were meticulously collected on 2024-11-27. The key metric for institutional ranking is the aggregated sum of D-indexes (Discipline H-index) of all qualifying scholars whose main area of publication is Computer Science and who are affiliated with a given institution. The D-index metric strictly incorporates publications and citations relevant to Computer Science, providing a discipline-focused measure of impact and research excellence.
Scope of Research and Data Selection Criteria
A total of 279,971 scientist profiles from a variety of bibliometric sources were reviewed for this edition. Out of these, 40,471 scientists specializing in Computer Science were systematically analyzed. To ensure the highest quality of data, only those scholars who met a D-index threshold of 30 (i.e., minimum discipline-based citation influence) and whose majority of significant publications reside within Computer Science were considered. Furthermore, each scientist’s professional triumphs, such as major awards and recognitions within Computer Science, were also factored into the selection process.
To properly distinguish top scholars, the D-index threshold for inclusion was incrementally adjusted by 10, based on the estimated total number of scholars in each discipline—effectively guaranteeing that the upper 1% of leading contributors are represented. An additional requirement ensured that the proximity between a scientist’s general H-index and their Computer Science D-index remained at or below 30%, further underscoring discipline focus. Notably, a scientist’s recognitions and accolades within their respective fields were supplemental factors in the ranking.
Verification Practices and Methodological Rigor
Recognizing the limitations of raw bibliometric data as absolute evaluative tools, the Research.com team undertook rigorous verification practices. Every scientist profile underwent manual verification and was cross-referenced with publication records from a wide range of trustworthy sources. This rigorous process guarantees reliability and reduces the risk of error or misattribution.
While a scholar's publication count in top-tier journals and conferences does not directly determine their position in the Research.com ranking, it remains an invaluable additional signal for evaluating individual contributions to Computer Science. The actual ranking position derives from each researcher's H-index, sourced specifically from OpenAlex and CrossRef—both recognized as leading bibliometric databases in the global research community.
