A colleague said to me today ‘oh that department has a number of factions’. Hmmm, did the data reflect this….I loaded data for just that department into Gephi (the data combined email, meetings, projects and hierarchy to deduce the social network). I ran Modularity and sure enough four partitions popped out. My colleague took a look at the names in each partition and said ‘yeah, looks about right’.
