Is anyone aware of the must read papers to get knowledge of the most recent algorithms and method for community detection in graphs, especially those that represent social networks?

    $\begingroup$ Girvan-Newman algorithm is a well-known algorithm and appeared in many research papers. You can find it in Wiki. $\endgroup$ – Bangye Dec 4 '14 at 23:33
  • $\begingroup$ Newman's Q-modularity also seems popular. But I think this question is problematic: on one hand, the literature on community discovery is quite large. On the other, while there is some overlap with theory, this is not really a theory question until you define "community" more precisely. $\endgroup$ – Sasho Nikolov Dec 5 '14 at 17:51

There's a recent paper [1] on dense subgraph (i.e. community) detection in the context of distributed computing. In [1], each node of the graph represents an operating entity (i.e. runs an instance of a distributed algorithm) and each node can communicate with its neighboring nodes by sending messages. The graph itself can change (slowly) over time. Note that the connections in social networks evolve over time, so considering a dynamic graph seems like the right model. By running a distributed algorithm, each node can locally determine whether it's part of a dense subgraph. You might want to consult the related work section of [1] to get pointers to other references.
