A RECOMMENDATION SYSTEM AND METHOD OF OPERATION THEREFOR

摘要

A recommendation system comprises a plurality of recommendation engines (101-107) which are coupled together by a data communication coupling (109). Each of the recommendation engines (101-107) comprises a user profile (203) for a first user, a prediction processor (201) for generating recommendations for the first user in response to the user profile and an interface (209) for exchanging recommendation event messages, such as a request for a recommendation and a reply thereto, with other recommendation engines on the data communication coupling. At least one of the user profile and prediction algorithm of at least some recommendation engines (101-107) are different. A recommendation processor (205) generates a recommendation in response to a received recommendation event message and a recommendation indication from the prediction means. The invention may provide improved recommendation by interworking of independent recommendation engines (101-107).
