João was a full-time PhD student in information retrieval at the

Department of Computing, Imperial College London, in the Multimedia and

Information Systems Group, supervised by Prof Stefan Rueger.

His PhD thesis http://people.kmi.open.ac.uk/stefan/www-pub/j.magalhaes-phd.pdf Statistical models for semantic-multimedia information retrieval, published in 2008, has improved multimedia search by exploring semantic-multimedia analysis through two complementary search...
