Visualisation of Observed and Expected cross-citations between Subject Categories (SCs)

of unit’s publications

Notes:Node size = Sum of citations from each Subject CategoryBlue links = Expected % of cross-citations from SCi to SCj(given the total number of references from SCi and given the average citation flows from SCi to SCj in the Web of Science)

Orange links = Observed % of cross-citations from SCi to SCj

Only links representing more than 0.2% citations are shown

Green Lines = Observed / ExpectedOnly links with Observed/Expected>5, and Observed>0.2% are shown
