Kurzfassung
In this paper, we introduce an expressive ontology-based model for representing resources with respect to a domain ontology. Our resource model is based on semantic web standards as well as established ontologies and metadata schemas such as SUMO, MPEG-7 and Dublin
Core to provide a reference model for ontology-based information retrieval. Based on this expressive resource model, the user can directly specify his information need at an enhanced level of expressiveness. In particular, it does not restrict the description of resources to keywords but allows for the
description of resources in terms of factual and terminological axioms as
well as events and complex situations. We show that with the proposed resource description model, a large set of different retrieval functionalities can be supported to address complex information needs.
