six indicators to rank universities globally

The ARWU uses six indicators to rank universities globally including the number of alumni and staff with Nobel prizes, the number of highly cited researchers, the number of articles published and cited in top journals and the per capita performance with respect to size of the institution.
From the Asia-Pacific region, the top performer was Tokyo University which was again listed in 20th place followed by Kyoto in 24th position. However Japan's overall performance was weaker with just 25 universities in the top 500, down from 31 last year.
