Institutional positions in the ranking are determined by the aggregate sum of D-indexes (Discipline H-index) of all qualified scholars whose principal publication domain is Computer Science and who are affiliated with a respective institution. The D-index is an adaptation of the H-index, calculated exclusively on publications and citations within a specified discipline, providing a precise measure of disciplinary impact.
Scope of Research and Inclusion Criteria
The current ranking is backed by a comprehensive analysis of 279,971 scientist profiles identified across a variety of bibliometric data sources. Specifically, 40,471 scholars with a primary focus in Computer Science were assessed for the final list. To qualify, a scientist must have achieved a minimum D-index threshold of 30, with the majority of their high-tier publications falling within Computer Science. In addition to quantitative bibliometric criteria, the evaluation also considered each scientist’s awards and achievements in the field.
The D-index threshold for inclusion as a top researcher is calibrated in increments of 10 according to the estimated population of scholars in each discipline. This approach ensures the inclusion of only the top 1% of leading experts. A proximity of 30% or less between a scientist’s general H-index and their D-index was also maintained to preserve disciplinary focus. Qualitative factors such as major awards and recognitions in Computer Science were incorporated to further differentiate leading contributors.
Additional Verification and Quality Assurance Practices
Recognizing that raw quantitative data is insufficient for holistic assessment, Research.com implements meticulous manual verification for all scientist profiles. These profiles are cross-referenced against a wide range of trustworthy publication sources to validate accuracy and completeness.
While the number of publications in leading journals and top-tier conference proceedings is not a direct ranking criterion, it is acknowledged as an important supplementary indicator of a scholar’s impact on the discipline.
Ranking positions are established using each researcher's H-index—specifically as reported by OpenAlex and CrossRef, the world’s most respected bibliometric databases. This reliance on industry-leading sources ensures that the ranking reflects an accurate and consensus view of scientific impact.

Research.com’s Mission and Agenda
The creation of the Research.com university rankings is rooted in our mission to inspire scientists, business leaders, and policymakers on a global scale. We strive to highlight emerging trends in scientific achievement, to foster the pursuit of excellence among scholars, and to provide the academic community with transparent and reliable tools to identify preeminent experts within various disciplines, countries, and institutions.
Key Results of the 11th Edition Ranking
The assessment has yielded significant insights into academic excellence in Computer Science both within Italy and globally:
- The top three Italian institutions by number of leading Computer Science scholars are:
- Polytechnic University of Milan – 39 scientists
- University of Bologna – 33 scientists
- Sapienza University of Rome – 29 scientists
- The most globally prominent Computer Science scholars are currently affiliated with institutions such as University of Montreal, Michigan State University, University of Oxford, University of California, Berkeley, University of Illinois at Urbana-Champaign, University of Illinois at Chicago, INSAIT, RWTH Aachen University, University of Granada, and Princeton University.
- Professor Yoshua Bengio (University of Montreal) is featured as the best scientist worldwide with a D-index of 223; Anil K. Jain (Michigan State University) ranks second (D-index: 214); and Andrew Zisserman (University of Oxford) holds the third spot (D-index: 197).
- The average total D-index for the top 5% of universities is 3383, compared to an average total D-index of 425 across all 1257 institutions assessed.
- The average number of published articles in Computer Science by scientists in the top 5% of institutions reaches 15,594, compared to an average of 2,216 for all ranked universities.
- The average citation count for the top 1% of universities is 2,279,971, far surpassing the overall average of 279,971 among all institutions in the dataset.
This meticulous and transparent approach offers an objective, detailed view of excellence within Italian and global Computer Science academia, empowering researchers, institutions, and policymakers alike to make data-driven decisions.
