The data above were extracted from
Clarivate'sEssential
Science Indicators database. This database, currently covering the
period January 1997 to December 2007, surveys only journal articles
(original research reports and review articles) indexed by Thomson
Scientific. Articles are assigned to a category based on the journals in
which they were published and Thomson Scientific’s
journal-to-category field definition scheme. Both articles tabulated and
citation counts to those articles are for the period indicated. Naturally,
institutions publishing large numbers of papers have a greater likelihood
of collecting more citations than scientists publishing fewer papers. This
ranking is by citations per paper (impact), among those institutions that
have collected 50,000 or more citations in chemistry.
For papers with multiple institutional addresses, each institution receives
full, not fractional, citation credit. This analysis reveals a strong
performance by US institutions, which take the first nine ranks and 13 of
20 in all. German institutions hold three spots, while UK universities
account for two. French and Swiss institutions appear once each. Essential
Science Indicators lists institutions ranked in the top 1% for a field over
a given period, based on total citations. For the current version, 858
institutions are listed in the field of chemistry, meaning that a total of
85,800 institutions were reviewed to obtain these results. Of the 858, 36
institutions collected 50,000 or more citations. The ranking by citations
per paper (impact) seeks to reveal “heavy-hitters” based on per
paper influence, not mere output.
