Formalisation des connaissances documentaires et des connaissances conceptuelles à l'aide d'ontologies : application à la description de documents audiovisuels

Abstract : The temporal nature of audio-visual force to use a description to enrich the documents with metadata and then exploit them. We defend that a representation of both the structure and the content of the documents is necessary. By structure, we mean the documentary structure, that is the mereological organization of the elements that compose the document, whereas the content refers to a conceptual structure, that is a categorization of these elements. After a review of the current propositions for modeling audio-visual documents, coming from the document engineering side and the knowledge representation side, we demonstrate that none of the studied languages can deal with these two aspects in a satisfactory way. We then propose a general architecture that allows to describe formally the structure and the semantics of audio-visual documents and that will generate a knowledge base on which we will perform some reasoning. This architecture is composed of an audio-visual ontology, whose a part is translated into a documentary language in order to control the logical structure of the document, and a domain ontology for describing the semantics of the content. We have developed the DOE tool (Differential Ontology Editor) that implements the chosen methodology for building the ontologies. Finally, we demonstrate the relevance of our approach with two experiments on an annotated corpus of video, showing hence the kind of inference we can make.
