.... either generating spatial information from numerical data [ Abella Kender 93; Andr e et al. 88; Gapp 94 ] or on understanding the meaning of a spatial description in the sense of visualizing verbally described spatial configurations [ Olivier Tsujii 94; Schirra Stopp 93; Hernandez 93 ] Stopp et al. 94 ] present a system for bi directional natural language communication with a robot. They address both, the generation of prepositions for LO RO pairs as well as the problem of localizing a LO w.r.t. a given RO and some preposition. However, in this approach, object recognition in the 2 D images ....

....match [21] and from different traffic scenes with vehicles [36] and a walking pedestrian [20] have been examined. In addition, application areas like intelligent multimedia systems [6] automatic route descriptions for driver support in road vehicles [29] and autonomous mobile robot systems [39] have been investigated as well. In all these scenarios it is crucial to be able to refer to spatial aspects of the domain under consideration, i.e. there is a common need for generating and understanding localization expressions. 2 From Visual Data to Spatial Descriptions In general, natural ....

In all these domains spatial descriptions play an important role. Here, we will concentrate on the Soccer domain with respect to the search for suitable spatial descriptions. As mentioned above, Soccer simultaneously ....
....These functions are adjustable to on going empirical experiments. In combination with RO dependent instantiation rules, for every instance of a spatial concept a proposition is created to which a degree of applicability can be applied with respect to the position of LO (cf. Gapp, 1994a; Stopp et al. 1994 ] We distinguish between three classes of static spatial relations which differ in the types of parameters according to their basic meaning: ffl Topological relations: These relations are only dependent on the so called local distance, i.e. the distance between LO and RO, scaled by the RO s ....

In order to realize these tasks the KANTRA system (KAMRONatural Language Translator) was developed based on work done in the VITRA project. So far, the focus was on the role of spatial relations in such a system [Stopp et al. 1994], especially for natural language task specification concerning implicit elementary operations [Langle and Luth, 1995, Langle et al. 1995] a) b) Figure 4: a) Error that is caused by uncertain position information, b) Error that must be recovered By the use of error recovery modules, it should be ....
