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 paradigms: (1) search-by-keyword and (2) search-by-semantic-example.
