Severe language effect in university rankings: particularly Germany and France are wronged in citation-based rankings
Abstract
We applied a set of standard bibliometric indicators to monitor the scientific
state-of-arte of 500 universities worldwide and constructed a ranking on the basis of these
indicators (Leiden Ranking 2010). We find a dramatic and hitherto largely underestimated
language effect in the bibliometric, citation-based measurements of research performance when comparing the ranking based on all Web of Science (WoS) covered publications and on only English WoS covered publications, particularly for Germany and France.
