Coping with the Intrinsic and Deictic Uses of Spatial Prepositions

چکیده
This paper1 deals with the definition of a computational semantics for spatial relations between objects in a scene. In particular we examine the effects of the observer's position on the computation of spatial relations, the use of path prepositions, and degrees of applicability for spatial relations. Representational prerequisites and the computational analysis of spatial relations are investigated in the German dialogue system CITYTOUR. This paper appeared in: K. Jorrand and L. Sgurev (eds.), Artificial Intelligence II: Methodology, Systems, Applications, pp. 375–382. Amsterdam: North-Holland, 1987. 1This report describes work done in the project VITRA, which is part of the SFB 314 Research Program of the Science Foundation (DFG) on AI and Knowledge-Based Systems.

Factors Affecting Spatial Deictic Communication: A Comparison of German and American English
The spatial prepositions ”in front of” or ”behind” can be used in different frames of reference; some determinants of their deictic and intrinsic uses are discussed. A series of experiments shows that both the intrinsic orientation of the reference object and the social characteristics of the situation significantly affect the production of utterances containing ”in front of” or ”behind”, or re...

which the primary object is located the reference object. In order to use projective prepositions, the speaker has to establish a reference frame (that is, an orientation) that determines the direction in which the primary object is located in relation to the reference object. The reference frame can be established in different ways. One way is to use the intrinsic orientation of the reference ...

In this paper we propose several formal tools intended to grasp an important aspect of static localisation in language namely orientation. We consider French spatial expressions used in localising an entity in an internal way (Internal Localisation Nouns such as haut (top), bas (bottom), devant (front), derrière (back)) or in an external way (prepositions devant (in front of), derrière (behind)...

A novel combination of ideas from cognitive linguistics and spatial occupancy models in robotics has led to the WIP (Words Into Pictures) system. WIP automatically generates depictions of natural language descriptions of indoor scenes. A qualitative layer in the conceptual representation of objects underlies a mechanism by which alternative depictions arise for qualitatively distinct interpreta...
