Data

Pacs – PACS (Physics and Astronomy Classification Scheme) network available here. For every paper that appeared in Physical Review A, B, C, D, E, Letters and Special Topics: Accelerators and Beams between 1977-2007, a link is included between the APS PACS codes that are referenced in the paper.

Using Cfinder, communities of scientific fields can be

identified using the PACS network. Nodes in the scientific

concept network shown on the right correspond to scientific

fields and edges between them signify the overlap between

the fields. The edge weights are correlated with the overlap

size. The node size is correlated with the size of the

community, hence the number of PACS codes contained

in the community.

Community structure shown in 1997 and 2006 with Cfinder, clique

number of 7 and paper lifetime of 2.5 years.

Data for the 1997 scientific fields network shown in Figure 1 with detailed

description.

Data for the 2006 network shown in Figure 2 with detailed description.
