CWTS Leiden Ranking

 

The CWTS Leiden Ranking is based on publication details from the Thomson Reuters' Web of Science database. The ranking  is based on articles and reviews; other types of publication are not considered. Moreover, only articles from English-language journals count, and some specific journals are excluded. A university has to have at least 500 publications published annually in order to be selected. You will find more information on the methodology behind this ranking system here.
 
The CWTS Leiden Ranking measures academic impact and collaboration between universities. Different settings can be used.  For example one can rank based on the top 1%, 10% or 50% most cited publications. One can also put a minimum to the scientific output and rank on a specific academic discipline.

Academic impact
The standard indicator for scientific impact is based on the top 10% of the most cited publications, taking all academic disciplines into account.  This explains why the more specialized Dutch universities have a relatively low ranking. Four Dutch universities are in the top 100 of this ranking.

It is also possible to rank universities based on the number of international publications. The ranking  can be adjusted here.
