American universities. In the 2014 rankings,
Rockefeller University was first by citation impact, as measured by both mean citation score and mean normalized citation score, as well as by the proportion of papers belonging to the top 10% in their field. Notably, the
University of Oxford, the
University of Cambridge, and other
British universities score much lower than in other university rankings, such as the
Times Higher Education World University Rankings and
QS World University Rankings, which are based in part on reputational surveys among academics. When measuring by collaboration with other universities (the proportion of number of publications co-authored with other institutions), the top three spots were occupied by
National Yang-Ming University and two other institutions from
Taiwan in 2014, followed by universities from
France, the United Kingdom and a number of other European countries.
King Abdulaziz University and
King Saud University in
Saudi Arabia led the list in 2014 when measured by international collaboration. == Indicators ==
