Domain Independent Semantic Representation of Multimedia Presentations

This paper describes a domain independent approach for semantically annotating and representing multimedia presentations. It uses a combination of techniques to automatically discover the content of the media and, though supervised or unsupervised methods, it can generate a RDF description out of it. The domain independence is achieved using Wikipedia as a source of knowledge instead of domain Ontologies. The described approach can be relevant for understanding multimedia content which can be used in Information Retrieval, categorization and summarization.
