Abstract : |
The topic of this paper 1 is the analysis of the semantics of the particular spatial relations 'along ' and 'past ' which are used to characterize the path of moving objects. The German dialogue system CITYTOUR, which answers questions about the spatial relations of objects in a scene, is presented by means of a simple dialogue example. The representational prerequisites of the static and the dynamic objects, required for computational analysis are presented. Two concrete predicate functions testing whether a dynamic object moves along or moves past a static object are described in detail., |
