Bio
I am interested in information retrieval (IR) in general, for instance in settings such as Web, Enterprise, social media and Smart cities, building upon observations from sensor). I regularly participate in TREC, and jointly co-ordinated the TREC Blog track from 2006-2010, the Microblog track (from 2011-2012), and the Web track (2014-). My thesis addressed access to expertise in enterprise environments, and was titled The Voting Model for People Search. I have since deployed an expert search system for the SICSA alliance of Scottish computing science schools.
