PHILADELPHIA and LONDON, July 7 /PRNewswire/ --

- Survey Identifies Highest Impact Institutions, 2003-2007

The Scientific business of Thomson Reuters today announced results of a study assessing high-impact research by the United Kingdom's top-cited institutions and researchers. In the May/June issue of Science Watch and on, Thomson Reuters analyzes data from its Essential Science Indictors to identify "high-impact papers" that rank among the top one percent most-cited, by field, for their respective years of publication, 2003-2007. From the resulting file of approximately 6,000 high-impact papers, Science Watch highlighted the institutions and researchers most heavily represented.

University of Oxford claims the top spot with an impressive 47,392 citations over the five-year period. Ranking second is the University of Cambridge with 44,140 citations, while Imperial College of London completes the top three with 41,042 citations.

For this survey, Thomson Reuters also analyzed 'citation impact' to provide another indicator of research influence in the scientific community. "Larger institutions publish more papers and therefore usually lead the pack when it comes to citations," said Christopher King, editor of Science Watch. "By measuring citation impact, we can highlight the important contributions smaller institutions make to scientific discourse."

According to the measure of citation impact (or average number of citations per paper), Wellcome Trust Sanger Institute produced the highest score with an average citation impact of 136.7. The European Bioinformatics Institute took second place with an average citation impact of 133.3; Cancer Research UK closely followed with an average of 130.7 cites per paper.
