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.
