The Leiden Ranking measures the scientific performance of 500 major universities worldwide. Using a sophisticated set of bibliometric indicators, the ranking aims to provide highly accurate measurements of the scientific impact of universities and of universities involvement in scientific collaboration... The Leiden Ranking does not rely on highly subjective data obtained from reputational surveys or on data provided by the universities themselves.
