These positions are the result of the indicator that uses the proportion of the university's publications that, in comparison with other publications in the same field and in the same year, belong to the 10% most cited, allowing institutions to be compared regardless of their size.
In terms of collaboration, measured by publications in partnership with other universities, UAlg ranks 73 in Europe and 148 worldwide, and in international collaborative publications UAlg performs very well, ranking 50 in Europe and 109 worldwide. UAlg's biggest highlight in this ranking is gender equality, with UAlg ranking 23th in Europe and 26rd worldwide for having a high proportion of scientific publications by female authors in relation to the total number of male and female publications.
