In the last case, the system should be able to construct itineraries suited to the tourist s interests. In this paper, a method for generating tourist itineraries in knowledge-based recommender systems is proposed. The method is based on a theoretical model that defines space-time relations among items of intangible cultural heritage (called events) and on transitive closure computation (of the relations), that is able to construct chains of events. The proposed method has been implemented in the T-Path recommender system, that suggests itineraries of cultural events occurring in the Apulia region.  a03029743 (ISSN); 3642169848 (ISBN); 9783642169847 (ISBN)
