The GRBS includes the following indicators:
The following indicators are used for university rating.
Total Pubs:Total number of publications during a 4-year time window
%Pubs in Top 25% SNIP: Percentage of Total Pubs published in source titles that are within top 25% of that subject area, based on the SNIP value of the last year in the time window.
Total number of citations within a 4-year time window to papers published in that time window.
% Pubs in top 25% Highly Cited:
Percentage of publications within the 4-year time window that are within top 25% highly cited publications of that subject area. Citations are counted within the 4-year time window.
H-Index (4 years):
A university having 4-year h-index of X means that at least X of their publications (during that 4-year window) have no less than X publications citing them (during that window). A 4-year h-index of a university is computed for a particular subject area. A complete definition of h-index can be found at here.
The following indicators are used to benchmark internationality of research conducted at the university.
Internationally Co-authored Publications:Number of publications in the 4-year window that are written in collaboration with at least one researcher from outside the country in which university in located.
Percent International Collaboration: Percentage of Total Publications with international co-authorship
Total Citations of Internationally Coauthored Publications:
Total number of citations received within the 4-year window by internationally coauthored publications in the 4-year window.
Citations received from papers authored (only) by researchers from outside the country in which a given university is located. This is a strong definition of international citations so that citations from internationally co-authored publications are not counted.
Percent International Citations:
Percentage of International Citations relative to Total Citations.
International Citations of Internationally Co-authored Publications:
International citations received by Internationally Co-authored Publications.
Measure of the impact a university's research is having outside the country in which it is located. It is defined as the ratio of International Citations to the total number of references made by the papers in a given field which are authored (only) by researchers from outside the country in which the university is located. The denominator normalizes for the size of the market of citations outside the country.
