Indexation et interrogation de photos de presse décrites en MPEG-7 et stockées dans une base de données XML

This paper describes a user interface, built on top of a web server, dedicated to index and query a catalogue of news photos described as MPEG-7 documents stored in an XML database. This interface has been developed within the framework of a French RNTL project called “Muse” which aimed at building an XML multimedia search engine associated with an XML repository. This paper focuses on the three main features of the interface: (i) semantic and visual indexing of photos which produces a MPEG-7 document (ii) data querying : queries are captured in query forms and translated into XQuery queries sent to the XML database through a mediator, (iii) answer presentation and classification.
