This paper introduces an approach to providing intelligent support through different devices to organize and make a generic sightseeing visit involving indoor (a Museum) and outdoor areas (the city historical centre). The goal is to provide users with access to a range of information via wired and wireless client devices. The support is based on user modelling techniques that can update informa...

Natural language understanding (NLU) is an important module of spoken dialogue systems. One of the difficulties when it comes to adapting NLU to new domains is the high cost of constructing new training data for each domain. To reduce this cost, we propose a zero-shot learning of NLU that takes into account the sequential structures of sentences together with general question types across diffe...

This paper addresses a spoken dialogue framework that helps users make decisions. Various decision criteria are involved when we select an alternative from a given set of alternatives. When adopting a spoken dialogue interface, users have little idea of the kinds of criteria that the system can handle. We thus consider a recommendation function that proactively presents information that the use...

This paper presents INTRIGUE, a prototype tourist information server that presents information about the area around Torino city, on desktop and handset devices. This system recommends sightseeing destinations and itineraries by taking into account the preferences of heterogeneous tourist groups (such as families with children and elderly) and explains the recommendations by addressing the grou...

In this study, a general theory of an objective sightseeing area or “open service field” is defined. The reasons for the difficulties encountered in conducting the survey on the open service field are then explained. Next, we present our approach to providing incentives in our research system in order to avoid the known difficulties. We then explain the open service field point of service (POS)...
