The goal of this subproject is to develop an interactive system that gives advice to drivers about likely destinations, such as restaurants and gasoline stations, that meet the driver's criteria. This will take the form of a conversational interface that carries out a dialog, in spoken language, with the user that helps him transform an initially vague query, like ``Where should I have lunch today?'', into a specific location. The system should also have the ability to adapt to the user's preferences, so that the human-machine dialog becomes more efficient over time.
We have developed an initial adaptive interface that operates in the restaurant domain and that takes written text as input. The current system stores previous interactions with a users in a case library, which it uses to select the order of questions and to recommend options the user will find attractive. We have designed and started to implement the successor system, which will support spoken interaction and a more flexible model of the dialog process.
