Coherence Defined as the Ratio of Mean Observed Distance of Cross-Citations over Mean Expected Distance of Cross-Citations
Visualisation of Observed and Expected cross-citations between Subject Categories (SCs) of unit’s publications Notes: Node size = Sum of citations from each Subject Category Blue 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 / Expected Only links with Observed/Expected>5, and Observed>0.2% are shown
