Qualitative models of spatial knowledge concern the description of both objects and their relative position in space. Qualitative models of positional information should be seen as models able to represent commonsense knowledge of space and not as a surrogate of quantitative models, which have a specific role in computer graphics and pattern recognition. Qualitative models are especially suitable for describing positions in geographic space and build Geographical Information Systems that simulate the mental processes of human beings. This chapter presents a conceptually unified theoretical framework, within which positional relations can be represented and spatial reasoning can be performed to infer qualitative knowldge.

Abstract
Qualitative models of spatial knowledge concern the description of both objects and their relative position in space. Qualitative models of positional information should be seen as models able to represent commonsense knowledge of space and not as a surrogate of quantitative models, which have a specific role in computer graphics and pattern recognition. Qualitative models are especially suitable for describing positions in geographic space and build Geographical Information Systems that simulate the mental processes of human beings. This chapter presents a conceptually unified theoretical framework, within which positional relations can be represented and spatial reasoning can be performed to infer qualitative knowldge.Pubblicazioni consigliate
