"Social Topologies from Email and Photos"
1:30pm - 3:30pm


As peoples' participation in social media increases, online social identities accumulate contacts and data. We need a mechanism for creating a succinct but contextually rich representation of a person's "social landscape" that would facilitate activities such as browsing personal social media archives, or sharing data with nuanced social groups. We formulate the social topology extraction problem as the compression of a group-tagged dataset and explore a 2000 person email dataset and a 500 person photo tag dataset.
