Abstract:
Descriptive network analysis, including centrality and connectivity, gives a clearer picture of how individuals in a social network interact with each other and who the influencing people are in a network, for example. In this study, we integrate descriptive network analysis with mixed integer programming (MILP) clustering. A MILP clustering model is applied to some sub-graphs generated from a publicly available Facebook network with determined articulation points. The number of articulation p points inside the clusters are used as the number of clusters, a user-defined parameter for the model. The MILP model is run after the articulation points are assigned to different clusters. The model results with assigning articulation points to different clusters are compared to the results without initial assignments. The initial assignments improved the model solution time by more than 70% on average, as well as improved the modularity metric by around 19% on average.
