Towards context-adaptive utterance interpretation

Abstract

In the tourism domain, a simple question such as "Where is the castle?" may be interpreted solely ELS ct request for the castle's location. More often, as our data indicate, such a question is used to ask for directions to the specified object. A felicitous response to such a request may depend not only on the questioner's current location but also on other contextual features, such as the weather, traffic conditions, mode of transportation, and time. This pa-per describes experimental results supplying factors relevant to such context dependent analysis and a corresponding model that can be employed to increase the conversational abilities of dialogue systems.
