RANKINGS -- From
the ISI Essential Science Indicators Home page, you can access the four Citation
Rankings options, which enable you to compare the rankings
of numerous scientists, institutions, countries, and journals in
22 scientific fields.
are four groupings of citation ranking data:
Rankings - Citation counts are a form of peer recognition and
generally reflect the dependence of the scientific community on
the work of individual scientists. It could be argued that highly
cited scientists form the essential core of scientific community.
Many highly cited scientists have also received peer recognition
in the form of honorific awards.
Rankings - Scientific research is performed within the context
of an institution, and thus the recognition afforded the individual
researchers affiliated with that institution is reflected in the
prestige and reputation of the institution as a whole. By aggregating
publications and citations at the institutional level we can measure
the institutional output and prestige attributable to the affiliated
Rankings - Countries vary in their level of scientific effort
as measured by publication and citation activity. The distribution
of effort is uneven, and dominated by the developed countries. The
level of activity is roughly correlated with national GNP or other
measures of economic output. Comparing countries on a citations
per paper basis can help correct for size (output) differences.
Rankings - Journals vary widely in prestige, influence, and
impact, and this is reflected in the citation counts to a journal.
ISI Essential Science Indicators provides a long-term citation
ranking for journals. A comparison with short-term citation behavior
can be made by consulting the ISI Journal Citation Reports®
product published by ISI.
