In recent years there has been an increase in tourist demand in Portugal, mainly in the north. When a tourist arrives the first time to a new place, he needs to do an exhaustive research on the region or receive recommendations through applications that exist in the market. TheRoute has as an objective the development of a recommender system of touristic routes, with special focus on the northern region of Portugal, but it can be used in other regions of Portugal or in other countries. It's an investigation project that has as an innovator aspect the recommendation of routes based in the personality traits os the tourist, and also takes into account the information of the context of the tourist and the surrounding environment. To accomplish these objectives where implemented two algorithms, one that aggregates preferences and one that makes the group formation. The proposed objectives were accomplished with the development of the preference aggregation algorithm and with the group formation algorithm.
