    Learning User Preferences for 2CP-Regression for a Recommender System

  • Original language description

    In this paper we deal with a task to learn a general user model from user ratings of a small set of objects. This general model is used to recommend top-k objects to the user. We consider several (also some new) alternatives of learning local preferencesand several alternatives of aggregation (with or without 2CP-regression). The main contributions are evaluation of experiments on our prototype tool PrefWork with respect to several satisfaction measures and the proposal of method Peak for normalisationof numerical attributes. Our main objective is to keep the number of sample data which the user has to rate reasonable small.
