Query: Mapping excellence in the geography of science: An approach based on
  Scopus data   As research becomes an ever more globalized activity, there is growing
interest in national and international comparisons of standards and quality in
different countries and regions. A sign for this trend is the increasing
interest in rankings of universities according to their research performance,
both inside but also outside the scientific environment. New methods presented
in this paper, enable us to map centers of excellence around the world using
programs that are freely available. Based on Scopus data, field-specific
excellence can be identified and agglomerated in regions and cities where
recently highly-cited papers were published. Differences in performance rates
can be visualized on the map using colors and sizes of the marks.
