RECOMMENDATION SYSTEM AND METHOD OF OPERATION THEREFOR
First Claim
1. A recommendation system comprising:
- a plurality of recommenders for generating recommendations in accordance with a user preference profile having a recommender specific representation, the recommender specific representation being different for different recommenders of the plurality of recommenders and each recommender of the plurality of recommenders further comprising translation data relating the recommender specific representation to a shared ontology,wherein at least a first recommender of the plurality of recommenders comprises;
a translation unit for generating first user preference data represented in accordance with the shared ontology in response to a first user preference profile of the first recommender and first translation data relating a first recommender specific representation of the first user preference profile to the shared ontology; and
a transmitter for transmitting the first user preference data to a second recommender of the plurality of recommenders,wherein the translation unit is further arranged to generate a confidence indication for at least some of the first user preference data and the transmitter is arranged to transmit the confidence indication to the second recommender.

Abstract
A recommendation system comprises a plurality of recommenders for generating recommendations in accordance with a user preference profile having a recommender specific representation. The recommender specific representation is different for different recommenders and each recommender comprises translation data relating the recommender specific representation to a shared ontology. A recommender comprises a translation unit which generates first user preference data in accordance with the shared ontology in response to a user preference profile and translation data relating the recommender specific representation to the shared ontology. In addition, a confidence indication for at least part of the user preference data is generated. A transmitter transmits the user preference data and the confidence indication to a second recommender. The second recommender may translate the received data into its recommender specific representation and combine the received data with locally generated user preference data. The invention may facilitate and/or improve sharing of user preference data.
