9. A computer-implemented method comprising: determining a similarity of a semantic projection of a set of interests of a first user to a semantic projection of a first resource, wherein the semantic projection of the set of interests of the first user and the semantic projection of the first resource conforms to a common semantic projection model, the determination including: determining a similarity of a semantic projection of a set of static interests associated with the first user to the semantic projection of the first resource; and determining a similarity of a semantic projection of a set of dynamic interests associated with the first user and a first context to the semantic projection of the resource; wherein the determination of the semantic interest of the first user for the first resource in the first context is based on the similarity of the semantic projection of the set of static interests associated with the first user to the semantic projection of the resource, and on the similarity of the semantic projection of the set of dynamic interests associated with the first user and the first context to the semantic projection of the resource; determining a semantic interest of the first user for the first resource in the 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 determining 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.
