Combining topological and size information for spatial reasoning
Information about the size of spatial regions is often easily accessible and, when combined with other types of spatial information, it can be practically very useful. In this paper we introduce four classes of qualitative and metric size constraints, and we study their integration with the Region Connection Calculus RCC-8, a well-known approach to qualitative spatial reasoning with topological...
متن کاملCombining Topological and Qualitative Size Constraints for Spatial Reasoning
Information about the relative size of spatial regions is often easily accessible and, when combined with other types of spatial information , it can be practically very useful. In this paper we combine a simple framework for reasoning about qualitative size relations with the Region Connection Calculus RCC-8, a widely studied approach for qualitative spatial reasoning with topological relation...
متن کاملCombining Topological and Directional Information for Spatial Reasoning
Current research on qualitative spatial representation and reasoning usually focuses on one single aspect of space. However, in real world applications, several aspects are often involved together. This paper extends the well-known RCC8 constraint language to deal with both topological and directional information, and then investigates the interaction between the two kinds of information. Given...
متن کاملSpatial Reasoning with Topological Information
This chapter summarizes our ongoing research on topological spatial reasoning using the Region Connection Calculus. We are addressing di erent questions and problems that arise when using this calculus. This includes representational issues, e.g., how can regions be represented and what is the required dimension of the applied space. Further, it includes computational issues, e.g., how hard is ...
متن کاملReasoning with Topological and Directional Spatial Information
Current research on qualitative spatial representation and reasoning mainly focuses on one single aspect of space. In real world applications, however, multiple spatial aspects are often involved simultaneously. This paper investigates problems arising in reasoning with combined topological and directional information. We use the RCC8 algebra and the Rectangle Algebra (RA) for expressing topolo...
