Characterizing Trajectories of Moving Objects Using Natural Language Path Descriptions. In: Proc. of the 7th ECAI, vol. 2, pp. 1-8, Brighton, UK, 1986.


The topic of this paper 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.
