Claim One:
1. A system comprising: a storage device to store a respective semantic projection for each of a plurality of resources, for each of a plurality of sets of user interests and for each of a plurality of user contexts, each respective semantic projection conforming to a common semantic projection model; and a processor to: determine a similarity of a semantic projection of a set of interests of a first user to a semantic projection of a first resource; determine a semantic interest of the first user for the first resource in a first context based on the similarity of the semantic projection of the set of the interests of the first user to the semantic projection of the first resource; and determine an interest measure associated with the first user, the first resource and the first context based on a rating prediction for the first user to the first resource in the first context and on the determined semantic interest of the first user for the first resource in the first context.
