GTU’s ScholarGPS 2025 Specialty Rankings (World)

What Is ScholarGPS?

   ScholarGPS is an international scientific evaluation platform that classifies academic institutions and researchers  under 14 major fields of study, 177 disciplines, and more than 350,000 specialties.  The platform does not use subjective measures such as surveys or reputation scores; instead, it generates its rankings entirely through quantitative methods based on publication count (productivity), citation count (impact), and h-index (quality) data. In its evaluations, citations are weighted according to the number of authors, while self-citations are excluded from the calculations. The platform’s “Lifetime” category covers all academic outputs produced by researchers throughout their careers.
