Introduction Social, technological and information systems can often be described in terms of complex networks that have a topology of interconnected nodes combining organization and randomness [1, 2]. We present examples of the use of FlowKit for constructing reporting and analysis workflows, including round-tripping results to and from FlowJo for joint analysis by both domain and quantitative . For 0.4, this algorithm behaves differently depending on network size: it slightly underestimates the number of communities of small networks and significantly overestimates it for large ones. Modularity OptimizationCommunity Aggregation . Identifying communities in such a huge network took only 152 minutes. First, it looks for "small" communities by optimizing modularity in a local way. 1. Mech.
