DLMedia: an Ontology Mediated Multimedia Information Retrieval System

We outline DL-Media, an ontology mediated multimedia information retrieval system, which combines logic-based retrieval with multimedia featurebased similarity retrieval. An ontology layer is used to define (in terms of a fuzzy DLR-Lite like description logic) the relevant abstract concepts and relations of the application domain, while a content-based multimedia retrieval system is used for feature-based retrieval. We will illustrate its logical model, its architecture, its representation and query language and the preliminary experiments we conducted.
