ABSTRACT

In this paper we deal with user preference learning to enable top-k querying. Input for learning is user overall rating of a sample set of objects. We introduce a new method which favours the higher rated objects. We present a method for evaluating the top-k query results according to this preferences favouring top of the list. We compare our method to several methods and evaluate experiments on a real data set.

Keywords: Preference learning, User preferences, Top-k querying.
