The LinkedTV Ontology
The LinkedTV ontology has been developed under the scope of the European Project LinkedTV. This project aims to make TV content and Web information seamlessly interconnected. This way, watching television while accessing Web content should be smooth and transparent to the viewer. Technologically speaking, this vision requires systems to be able to represent television information as is done today in the Web of Data: interlinked other resources at different granularities, with any other kind of information, searchable, and accessible everywhere and at every time. Here is where the LinkedTV ontology plays its role. The LinkedTV ontology defines a list of classes that can be relevant in the vast domain of television content, like for example Chapters, Scenes, Concepts, Objects, etc. This model relies on other stablished and well known ontologies like the The Open Annotation Core Data Model, the Ontology for Media Resources, the NERD ontology, or the Programmes Ontology. In this ontology, television content can be annotated not only at the upper level of the entire program but also with different degrees of granularity, thanks to the use of the Media Fragments URI 1.0 specification. The instances of the MediaFragment class are the anchors where the other information is attached: legacy metadata from the providers, results obtained by automatic analysis of the video file, and even more important, links it to other resources in the Web where extra information about the content can be found.
