Uncertainty Extensions to Ontologies as a Tool for Semantic Interpretation in Audiovisual Systems

Abstract — This paper deals with semantic interpretation of audiovisual data. It investigates how explicit interpretation of uncertainty can help to bridge the semantic gap. We present a case study of FuzzyOWL — a current uncertainty representation framework — applied in the context of the recent European project CARETAKER focusing on automated situation awareness, diagnosis and decision support. A particular user-oriented task is modelled in FuzzyOWL. The paper briefly summarizes basic features of the formalism, discusses pros and cons and points out difficulties and problems connected to its employment.
