Integrating Complex User Preferences Into A Route Planner: A Fuzzy-Set-Based Approach

Route planners are systems which help users select a route between two locations. In such a context, personalization mechanisms notably aim at taking into account user preferences so as to identify the best route(s) among a set of possible answers. In this paper, we present a framework based on fuzzy set theory for modeling complex user preferences. We provide a typology of preferences which make sense in the domain considered and outline a query language integrating such flexible features. The paper also includes a discussion about query evaluation.
