Click on Eigenfactor´s map to enlarge
The social sciences, 2004
Orange circles represent fields, with larger, darker circles indicating larger field size as measured by eigenfactor. Blue arrows represent citation flow between fields. An arrow from field A to field B indicates citation traffic from A to B, with larger, darker arrows indicating higher citation volume.
The map was creating using our information flow method for mapping large networks. Using data from Thomson Scientific's 2004 Journal Citation Reports (JCR), we partitioned 1431 journals connected by 217,287 citations into 54 modules. For visual simplcity, we show only the most important links, namely those that a random surfer traverses at least once in 2000 steps, and the modules that are connected by these links.
