The paper titled "What makes the social search efficient," by Amr Elsisy, Buster Holzbauer, Boleslaw K. Szymanski, Miao Qi, and Alex Pentland was posted in arXiv. The paper  sheds a new light on social routing though friends of friends. The original idea of the small world first put forth by Milgram in the 1960s shows empirically how people knowing reliably only connections to...

Today, Prof. Boleslaw K. Szymanski presented a talk titled "Finding Efficient Spreaders for Information Diffusion in Social Networks" at Google in Mountain View, CA. The research presented in the talk was inspired by recent global events and their poor predictability that are often attributed to the complexity of the world event dynamics. To improve the predictability, we use a...

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...
