5th International Conference on Spoken Language Processing
Spatial reasoning plays an important role in many spoken dialogue systems. One application area where it is especially important is timetable information for local bus traffic. Users of such systems often request information based on vague spatial descriptions and a usable system must be able to handle this. We have extended a dialogue system with abilities to transform vague spatial expressions into a form that can be used to access the information base. In our approach we use the power of a Geographical Information System (GIS) for the spatial reasoning.
