VidOnt: a Core Reference Ontology for Reasoning over Video

Multimedia reasoning, which is suitable for, among other things, multimedia content analysis and high-level scene interpretation, relies on the formal and comprehensive conceptualization of the represented knowledge domain. Video and video-related ontologies, however, are not exhaustive in terms of concept coverage, redefine basic terms against Semantic Web best practices, and do not define complex role inclusions and role interdependencies. In fact, most previously released multimedia ontologies do not have a role box, and implement only a basic subset of the logical constructors available in the most common implementation language, OWL. Hence, they are not suitable for advanced reasoning tasks. To address some of the above issues, this paper describes a core reference ontology for video, formally grounded in one of the most expressive decidable description logics, and implemented in OWL 2.
