Output Total number of documents published in scholarly journals indexed in Scopus.
% IC. International Collaboration Institution’s output ratio produced in collaboration with foreign institutions. The values are computed by analyzing an institution’s output whose affiliations include more than one country address.
NI. Normalized Impact Normalized Impact is computed using the methodology established by the Karolinska Intitutet in Sweden where it is named “Item oriented field normalized citation score average”. The normalization of the citation values is done on an individual article level. The values (in %) show the relationship between an institution’s average scientific impact  and the world average set to a score of 1, –i.e. a NI score of 0.8 means the institution is cited 20% below world average and 1.3 means the institution is cited 30% above average.
% Q1. High Quality Publications Ratio of publications that an institution publishes in the most influential scholarly journals of the world, those ranked in the first quartile (25%) in their categories as ordered by SCImago Journal Rank (SJRII) indicator.
Spec. Specialization Index The Specialization Index indicates the extent of thematic concentration /dispersion of an institution’s scientific output. Values range between 0 and 1, indicating generalist vs. specialized institutions respectively. This indicator is computed according to the Gini Index used in Economy.
% Exc. Excellence Rate Excellence rate indicates the amount (in %) of an institution’s scientific output that is included into the set of the 10% of the most cited papers in their respective scientific fields. It is a measure of high quality output of research institutions .
% Lead. Scientific Leadership Leadership indicates an institution’s “output as main contributor”, that is the number of papers in which the corresponding author belongs to the institution.
% EwL. Excellence with Leadership Excellence with Leadership indicates the amount of documents in the Excellence rate in which the institution is the main contributor
