Social Algorithms at MSR-SVC

This is an umbrella project for several related efforts at Microsoft Research Silicon Valley in the areas of social network analysis and human computation.

Social networks

  • Inferring latent (dis)similarities in the observed social network
    MSR people: Ittai Abraham, Shiri Chechik, Moises Goldszmidt, Alex Slivkins
    External collaborators: David Kempe, Joseph Bradley
    It is commonly assumed that individuals tend to be more similar to their friends than to strangers. We view the observed social network as a noisy signal about the latent "social space": a structure that captures in what ways and to which extent the individuals are (dis)similar. This naturally raises the inverse question: given a social network, how accurately can we reconstruct the social space?
  • Incentives for information propagation in network
