Metadata trust in a personal video recorder

Trust is the belief or confidence in someone that their recommendations will work for you, i.e. that you will like the TV-programs (or other content) that they recommend. Many systems incorporate some notion of trust. Trust is more than similarity in taste, which makes trust a broader concept than the concept of similarity used in Collaborative Filtering. This paper describes ongoing work on the development of a trust-aware Personal Video Recorder (PVR). It presents a taxonomy of ways in which trust can be quantified and gives first ideas about automatically deriving trust for use in a PVR system.
