University of Sydney tops world science rankings

30 September 2011

The University of Sydney has been ranked first in Australia, first in the Oceania region, and 53rd in the world in the SCImago Institutions Rankings World Report 2011, which measures international rankings of scientific output.

The SCImago Institutions Rankings (SIR) World Report 2011 was released on 29 September 2011 by the SCImago Research Group, in Madrid, Spain.

The SIR rankings analysed scientific output, international collaboration, thematic specialisation and scientific impact for 3,042 research institutions around the world including universities, government agencies, research hospitals and major companies.

The University of Sydney ranked four places higher in the international ranking than the University of Melbourne, which ranked second in the Oceania region, and twenty four places higher than the University of Queensland, which ranked third in the Oceania region.

Having topped the regional rankings last year as well, the University of Sydney held its place from 2010 across all three scales of ranking.

The rankings are of institutions that published at least 100 scientific papers in scholarly journals in 2009 and analyses their scientific output during the period 2005-09 in the largest scientific literature database - Scopus from Elsevier.

The ranking includes six key performance indicators to evaluate institutions' research outcomes:

  • Output, measured as the number of scientific papers according to Scopus
  • International Collaboration, measured as the ratio of scientific documents an institution publishes in collaboration with foreign institutions
  • Normalised Impact, as the citation rate an institution receives compared to the World Average (according to the normalised citation indicator developed at Karolinska Instituet in Sweden)
  • Publication Rate into the 25% of 'Best Journals' according to SJR indicator developed by SCImago Research Group
  • Specialisation Index, value indicating the thematic concentration (close to 1)/dispersion (close to 0) of an institution's scientific output
  • Excellence Rate, proportion of an institution's scientific output found in the set formed by the 10% of the highly cited papers in their respective fields.

"It's wonderful that the University of Sydney's scientific research output has been ranked once again as top in Australia and Oceania, and 53rd internationally. We place special focus on fostering research excellence in the sciences, so it's great to have this international recognition of our research strength," said Professor Trevor Hambley, Dean of the Faculty of Science.

"The Faculty of Science can be extremely proud of our strong research track record, which has contributed to this SCImago ranking result," said Professor Hambley.

Following the University of Sydney, University of Melbourne and University of Queensland, other Australian institutions that ranked highly in the international list were: UNSW - fourth in Australia and the region, 87th in the world; Monash University - fifth in Australia and the region, 117th in the world; Australian National University - sixth in Australia and the region, 172nd in the world; University of Western Australia - seventh in Australia and the region, 236th in the world; and the CSIRO - eighth in Australia and the region, 239th in the world.

The SCImago Research Group state that the list is the world's most comprehensive and broadest research ranking of worldwide universities and research institutions. The 2011 report is the third edition of the SIR World Report, with the previous reports released in 2009 and 2010.
