Recognizing Expertise

A difficult issue with understanding face-to-face interactions is the lack of context information. Badge-like wearable sensors, for instance, can now tell us who talks to whom, but the context of these interactions (work? social?) likely trumps any content or conversational dynamics information. In this paper we detail a study where we have automatic annotations of work context information. We find that this leads to different indications of effective social structure in corporate contexts, showing that behavior during tasks drives the predictive strength of aggregated data. Finally we describe how behavioral features collected with the Sociometric Badge are being used to create a real time feedback system.
