Collaborative preference elicitation

Abstract

The inherent inaccuracies in user modelling and the use of non-deterministic algorithms means that Preference Elicitation systems are often unsatisfactory for users. We address this issue using a technique called collaborative elicitation. Leveraging the fact that humans rarely have unique preferences, we minimize explicit elicitation from users while attempting to improve user satisfaction. We categorize users into groups using collaborative techniques based on Von Ahn's "Games with a purpose." We then allow groups of users to collectively select default preferences for their peers.
