We designed a role ontology-enhanced multimedia search engine where the user can search and subsequently filter news items with queries and filter options describing the roles of the people who appear in the items, specifically politicians.The system makes use of a separate knowledge base with domain information on politics.We demonstrate that when a user fails to recollect the name of a politician, role-based queries combined with filter options tailored to the query and the result set, lead the user fast to both the name he failed to recollect and the intended results in the multimedia database.
