This talk provides an overview of several recent projects in modeling
social data, including user demographics, social network structure,
and temporal behavior. First, we present a study which pairs browsing
histories for 250,000 anonymized individuals with user-level
demographic data to study variation in Web activity among different
demographic groups. Next, we discuss work with the Yahoo! Mail team
which aims to infer associations and groups amongst and individual's
contacts. We conclude with an interpretable temporal model of
communication patterns which, phrased as a hidden Markov model,
provides an effective and interpretable characterization of both human
and non-human activity.
