Hootle

Hootle is a hotel recommender system developed to study an approach to group recommendations from the point of intersection of traditional group recommenders and group decision making theory.

The system allows users to collaboratively create a preference model, from which recommendations are generated. In this process, group interaction can happen at two stages: (1) users can online discuss and negotiate preferences stated by others, and (2) they can discuss and rate items taken from the recommendation set to arrive at a final consensus decision.
