Folks in Folksonomies at WSDM 2010

Fil will present the paper Folks in folksonomies: Social link prediction from shared metadata (authored with Rossano Schifanella, Alain Barrat, Ciro Cattuto, and Ben Markines) at WSDM 2010 in New York on February 5. The paper discusses homophily, or more specifically the relationship between social connections and social tagging in folksonomies. We show that social similarity measures based on annotations can be effective predictors of friendship relationships. For the occasion, we are making our dataset publicly available.
