Figure 5.3.2 presents the number of open access publications and their citations for each institutional category, as well as the relevant field-normalised citation score, corresponding to the 5-year period 2014-2018. When referring to the field normalised citation score or “citation score”, we point out to the number of citations that publications per institutional category received compared to the world average of citations received over the same time period and per scientific field. The normalisation was processed at the level of each publication according to the 253 NSI scientific subject fields. In the case that an article would be categorized in more than one subject fields, a mean value for the fields was calculated. The citation score was calculated using software developed by EKT. A value greater than 1, indicated that the impact of publications was higher than the world average.

Publications of GSRT Research Centers achieved the highest citation score with a value of 1.63, which is higher than the world average.
