On November 21, 2022, Research.com released the first edition of the annual online ranking for the best universities in the world. The ranking is unique, as its main focus is on measuring the influence and contributions of researchers and scholars from each institution, based on objective data reflecting the reputation of academic scholars, a metric that is frequently missing from other popular rankings.
What is more, we hope it will inspire researchers, decision-makers, and entrepreneurs around the world to find out where leading experts work and carry out their research. It is a great opportunity for all of us to learn which institutions and countries host the leading experts in all areas of science.
For the 2022 edition of the online ranking, more than 166,880 scientist profiles on Google Scholar and Microsoft Academic Graph have been examined with several indicators and metrics reviewed in order to consider each scientist’s inclusion in the ranking.
The position in the ranking is based on a total sum of H-index values from Microsoft Academic Graph for scientists affiliated with a given university. The H-index threshold for approving a scholar to be considered was set differently for each scientific discipline but was in most cases equal to 30 or 40. The inclusion criteria for scholars to be considered for the ranking of top scientists are based on their H-index, the proportion of contributions made within the given discipline, and the awards and achievements of the scientists.

Professor Imed Bouchrika, the co-founder and chief data scientist at Research.com, explained the reasons behind creating the ranking:
“Because of the need to have a transparent methodology based on rational and well-established metrics, it’s without a doubt that the main contributor to success for an institution stems from the reputation of its staff. Besides, when it comes to tertiary education, research is the thrust for such success. The rankings of universities based on objective data compiled from top scientists would serve to produce a fair framework for ranking academic institutions where students can have the opportunity to be educated and supervised by leading scholars. It was unfortunate to spot numerous prestigious universities with a considerable number of leading scientists being poorly ranked by other mainstream ranking providers.“
