In this paper, the authors describe and evaluate Hippalus, a system that offers exploratory search enriched with preferences. Hippalus supports the very popular interaction model of Faceted and Dynamic Taxonomies (FDT), enriched with user actions which allow the users to express their preferences. The underlying preference framework allows expressing preferences over attributes (facets), whose values can be hierarchically valued and/or multi-valued and offers automatic conflict resolution. To evaluate the system they conducted a user study with a number of tasks related to a "Car selection" scenario.
