Subject Rankings

IBM Corporation Subject Rankings 2025

AD Scientific Index (Alper-Doger Scientific Index) offers the broadest spectrum of branches, providing analysis in 13 main fields and 197 sub-branches at global, national, and regional levels. These analyses can be based on indicators such as the H-index, i10-index, and citation count, as well as their values from the last 6 years. As of Dec 18, 2024, rankings are according to the Total H Index. BETA VERSION: The subject field rankings for the world, regions, countries, and universities are currently in beta. This is due to the exclusion of (873.898) scientists categorized under 'others,' whose profiles cannot yet be determined, edited, or classified. As these fields are updated, the rankings will adjust accordingly. Please keep this in mind. See Also: [University Subject Rankings]
