Deliverable D2.4 Annotation and retrieval module of media fragments

This deliverable presents an update of the LinkedTV metadata model as part of the WP2 of the LinkedTV project. It includes a set of mappings with other ontologies such as LUMO used in WP4. Second, we describe the converter module named TV2RDF, implemented as a REST service, that populates the LinkedTV triple store with RDF data resulting from the automatic conversion of legacy metadata provided by the content provider, of automatic analysis results generated by WP1, and of named entity recognition and disambiguation applied on subtitles provided with the content. Third, we describe the model and the service that aims to provide enrichments for particular media fragments of a seed video content. Finally, we present a number of useful SPARQL queries that are typically needed by the LinkedTV player or other clients that wish to reuse this semantic dataset
