Semantic personalisation in networked media: determining the background knowledg

This paper examines the requirements and argues about the features that an ontological knowledge base should encompass in order to represent semantic information pertinent to a user and suitable for context-aware preference elicitation and content recommendation. It explores existing formal ontologies suitable to represent user characteristics and the diverse information in digital media, as well as the opportunities and shortcomings that linked open data vocabularies bring into play. Based on these aspects, the paper concludes with the reasoning behind the composition of an appropriate reference ontology for the personalisation task of the LinkedTV EU project.
