Many rankings that try to classify universities, according to their scientific production, use the number of published and indexed papers in a recognized database. However, it is not balanced to compare the number of articles produced by a university that has 20 professional careers versus a university with only five professional careers. In this sense, in this work, we propose not only to use the number of papers but to divide it by the number of professors. The idea is to balance the comparison between universities of different sizes. As results, a significant variation in the order of the universities was obtained between a ranking that considers only the number of papers and the ranking that we propose where we also consider the number of professors.
