  • 4. RECOMM. SYSTEM DEFINITION
    • Recommender systems are a specific type of information filtering (IF) technique that attempt to present to the user information items ( movies , music , books , news , web pages ) the user is interested in.
    • To do this the user's profile is compared to some reference characteristics. These characteristics may be from the information item (the content-based approach) or the user's social environment (the collaborative filtering approach).
  • 5. TA XONOMY
  • 6. COLLABORATIVE FILTERING
    • Collaborative filtering (CF) is the method of making automatic predictions (filtering) about the interests of a user by collecting taste information from many users (collaborating). The underlying assumption of CF approach is that those who agreed in the past tend to agree again in the future. For example, a collaborative filtering or recommendation system for music tastes could make predictions about which music a user should like given a partial list of that user's tastes (likes or dislikes).
