This map is based on research-front data for the six-year period ending in
August 2009. The map shows the major subject areas within fields linked together
in a network based on the same principles as our research-front maps showing
highly cited papers. To create a map of science, we start with all research
fronts in
Essential Science IndicatorsSM
from Thomson
Reuters, and compute the links between fronts based on how often they
are co-cited—that is, the frequency that current papers jointly cite two given
fronts. Successive applications of a clustering process then groups fronts into
larger aggregates. Each circle on the map represents a cluster or aggregate of
research fronts on a broad topic within that field. Annotations have been added
to this map which represent the main research themes. These appear as labels
attached to specific regions on the maps.
