Well-connectedness of communities: Park et al show that many communities detected with standard algorithms are not well-connected: by cutting a few edges, such a community breaks into 2. Remedy by post-processing.

Well-connectedness and community detection
Author summary Community detection—a term interchangeably used with clustering—is used in network analysis. An expectation is that communities or clusters should be dense and well-connected. However, density is separable from well-connectedness, as clusters may be dense without being well-connected. Our study demonstrates that several clustering algorithms generate clusters that are not well-connected according to a mild standard we impose. To address this issue, we developed the Connectivity Modifier (CM), a tool to allow users to specify a threshold for well-connectedness and enforce it in the output of multiple community detection methods.
