Online social media have democratized the broadcasting of information, encouraging users to view the world through the lens of social networks. The exploitation of this lens, termed social sensing, presents challenges for researchers at the intersection of computer science and the social sciences. The unprecedented connectivity afforded by social media also gives rise to...

The paper generalizes inference algorithms to search not only for assortative communities but also for disassortative clustering. The maximization of generalized modularity performs well on networks in which the members of all communities are statistically indistinguishable from each other. However, there is no theory defining the maximization performance in more realistic networks...
