This paper presents a web based recommendation system aimed at supporting a user in building a personalized travel plan. A travel plan bundles together elementary travel components that are selected by the user in a mixed initiative way: the user poses queries and the recommender helps the user to reformulate the query and finally ranks the selected items. This paper concentrates on the methodological aspects that enable the interactive query refinement of the user queries, and in particular the intelligent relaxation of query constraints in case the query returns no items.

Abstract
This paper presents a web based recommendation system aimed at supporting a user in building a personalized travel plan. A travel plan bundles together elementary travel components that are selected by the user in a mixed initiative way: the user poses queries and the recommender helps the user to reformulate the query and finally ranks the selected items. This paper concentrates on the methodological aspects that enable the interactive query refinement of the user queries, and in particular the intelligent relaxation of query constraints in case the query returns no items.File in questo prodotto:
