With regard to the 5-year period 2006-2010, Figures 4.3.1 and 4.3.2* display the number of publications and citations as well as the relevant “field-normalised citation score” for each University. The field normalised citation score or “citation score” is the relative number of citations to publications of a University compared to the world average of citations to publications of the same time period and scientific subject field. The normalisation was done on an individual article level according to the 253 NSI scientific subject fields. If an article was originating in more than one scientific fields, a mean value of the fields was calculated. The citation score was calculated using software developed by the National Documentation Centre (EKT). A value greater than 1, indicated that the impact of publications was higher than the world average.

Citation score’s values and the number of Universities approaching the world average indicate a better performance when compared to those of  the preceding years. The Technical University of Crete/ TUC, the University of Crete/UOC, the University of Ioannina/UOI and the Harokopio University of Athens/HUA ranked first, exceeding the world average (citation scores 1.11, 1.08, 1.04 and 1.01 respectively). The citation score was approaching the world average with values over 0.9 - for the University of Piraeus/UNIPI (0.95), the Agricultural University of Athens/AUA (0.94) and the University of Western Macedonia/ UOWM (0.90)-
