Research Fronts and Research Front Maps
Research fronts are clusters of highly cited papers and research front
maps are diagrammatic representations of the co-citation links among
the highly cited papers that comprise the cluster. Fronts are selected
from the Research Fronts section of
Essential Science IndicatorsSM from
which is updated every two months. Some maps also link to author
commentaries for specific papers.
Each circle represents a highly cited paper whose bibliographic
information is displayed when the user clicks on the circle. The solid
lines between circles represent the strongest co-citation links for
each paper (that is, indicating that the papers are frequently cited
together); weaker links are indicated by dashed lines. Papers close to
each other on the map are generally more highly co-cited. The most
recent paper(s) are indicated in pink or yellow depending on the map.
