Research Front Maps from Thomson Reuters

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 Indicators from Thomson Reuters 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.
