Release of the CWTS Leiden Ranking 2015
Today CWTS has released the 2015 edition of the Leiden Ranking. The CWTS Leiden Ranking 2015 offers key insights into the scientific performance of 750 major universities worldwide. A sophisticated set of bibliometric indicators provides statistics on the scientific impact of universities and on universities' involvement in scientific collaboration. The CWTS Leiden Ranking 2015 is based on Web of Science indexed publications from the period 2010-2013.
Improvements and new features in the 2015 edition
Compared with the 2014 edition of the Leiden Ranking, the 2015 edition includes a number of enhancements. First of all, the 2015 edition offers the possibility to perform trend analyses. Bibliometric statistics are available not only for the period 2010-2013 but also for earlier periods. Second, the 2015 edition of the Leiden Ranking provides new impact indicators based on counting publications that belong to the top 1% or top 50% of their field. And third, improvements have been made to the presentation of the ranking. Size-dependent indicators are presented in a more prominent way, and it is possible to obtain a convenient one-page overview of all bibliometric statistics for a particular university.
Differences with other university rankings
Compared with other university rankings, the Leiden Ranking offers more advanced indicators of scientific impact and collaboration and uses a more transparent methodology. The Leiden Ranking does not rely on highly subjective data obtained from reputational surveys or on data provided by universities themselves. Also, the Leiden Ranking refrains from aggregating different dimensions of university performance into a single overall indicator.
