Productivity Rankings is a unique service offered only by “AD Scientific Index”. This is a ranking system derived from the i10 index in order to show the productivity of the scientist in publishing scientific articles of value. Productivity Rankings is an instrument that lists productive scientists in a given area, discipline, university, and country and can guide the development of meaningful incentives and academic policies. The world rankings, regional rankings, and university rankings of scientists in this table are developed based on the total i10 index. Additionally, click to view the special rankings based on Productivity Rankings: Scientists Last 6 years' i10 Index", Universities Total i10 Index Rankings 2025, Universities Last 6 Years i10 Index Rankings 2025 "Art and Humanities i10 Productivity Rankings" and "Social Sciences and Humanities i10 Productivity Rankings".
