Classical Recom-menders are based only historical data and also suffer from several problems linked the lack of such as sparsity. Users’ reviews represent a massive amount valuable rich knowledge information, but they still ignored by most current recommender systems. Information users’ preferences contextual c...

Context-aware systems enable the sensing and analysis of user context in order to provide personalized services to users. We observed that it is possible to automatically learn contextual factors and behavioral patterns when users interact with the system. We later utilize the learned patterns to infer contextual user interests within a recommender system. We present a novel context-aware model...

Given annotation knowledge-bases, explicit background knowledge in the form of ontologies, a user model capturing the user’s behavior and context, the system produces recommendations. Ontology-based user profiling can be used to reduce cold-...
