Multidimensional visualization system for travel social networks

In this paper we provide a multidimensional visualization system for travel social network. This system allows to analyse the structure and the social aggregation of travel networks providing different perspectives according to three dimensions: the space that defines locations connected to the members; the time that defines temporal evolution about tourist interests of the members; and coordinates involving classes of interests that define typologies of tourism chosen by members. Furthermore the system offers location-based tourist services providing a spatial visualization of the services connected to the specific place and sharing information about specific place. Finally in order to evaluate the proposed method, interviews to tourists and stakeholders were carried out after testing of the system.
