Thomson Reuters has developed co-citation methodologies over the years and employs it in its Essential Science IndicatorsSM database to construct so-called research fronts. A research front consists of a group of highly cited papers that are co-cited, meaning the core papers are cited in pairs. By collecting the core papers cited pairwise (A and B, B and C, C and D, D and A, C and B, B and D, A and C, and so on depending on the size of the core literature), a cluster of highly related papers can be identified. These typically represent subspecialties. By examining the average age (mean year) of the co-cited core papers, hot research fronts emerge. A hot research front, in which the core, or foundation, papers are of recent vintage, suggests new, rapidly developing areas.

The table above lists a selection of hot research fronts, ranked by the mean year of the core papers. These were chosen for their age, size, and apparent weight within their representative subject areas. Science magazine recently named the area ranked fifth, which it termed “Reprogramming Cells”, as its Breakthrough Area of Year for 2008 in its 19 December 2008 issue. It also listed the field ranked second as a runner-up.

See Research Front Maps for additional information. 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 which is updated every two months. Some maps also link to author commentaries for specific papers.
