Participants : Nicolas Béchet, Yves Lechevallier [resp.] .

This work is done in collaboration with Marie-Aude Aufaure (Ecole Centrale de Paris, Business Intelligence Chair),

Addictrip.fr is a website created by the Cassette Voyage company. The goal of the Addictrip project is to produce a recommender system in the e-Tourism field. It focusses on a new travelers requirement: the city breaks. The assumption is to provide short breaks in major cities by offering stays in hotels at attractive prices. Addictrip collaborates with various partners as “booking” or “Venere” in order to propose a various choice of hotels.

Two main tasks in the contract AxIS-Cassette (OSEO-4997) started in september were needed to make these recommendations: computing of user profiles according to visited hotel web-pages (to realize this task, we used AWLH produced in the AxIS project) and computing hotel profiles based on the construction of an ontology of the hotel business field (We first manually build concepts of ontology by using the services of two representative partners. Then we proposed an approach to automatically expand ontology by adding services from other partners).
