Recommendation of travelling plan for elderly people according to their abilities and preferences

To recommend a travel plan for elderly people, we have to consider more constraints related to ability and health. Existing Web services of travel do not consider these constraints. In order to enhance the quality of live (QoL) of elderly people, we propose a pattern Web service, which takes into account these constraints. Our goal consist to use advantage of semantic Web in order to consider fully user constraints and preferences. We present in this paper, a method of collaboration between request, profile and tourism models to elaborate a recommendation system, which allows to select the travel plan according to user ability. This latter is described by the user profile. The models base on the semantic description of all: user profile, user request and tourism data base. In addition, both of existed user profile ontology and tourism ontology have to be extended to consider constraints and preferences of elderly people.
