DIMENSIONS OF QUALITATIVE SPATIAL REASONING
Christian Freksa, Ralf Röhrig · 1999
Qualitative knowledge can be viewed as that aspect of knowledge which critically influences decisions. Reasoning with qualitative knowledge has been studied extensively for the temporal domain. It turns out that the spatial domain is considerably richer than the temporal domain. The richness of the spatial domain is illustrated by showing the design choices for qualitative reasoning systems. After a general discussion of these dimensions of spatial knowledge nine research projects are presented for a comparison of their adaptation of qualitative methods to the domain of space. A classification with respect to the dimensions of spatial knowledge is presented and discussed. 1. QUALITATIVE REASONING IN ARTIFICIAL INTELLIGENCE Qualitative reasoning is becoming increasingly popular in Artificial Intelligence (AI) and its areas of application. Various factors contribute to this development, including the following insights: 1) High-precision quantitative measurements are not as universally...
