A Hybrid Reasoning Model for "Whole and Part" Cardinal Direction Relations
In our previous papers [Kor and Bennett, 2003; 2010], we have shown how the nine tiles in the projection-based model for cardinal directions can be partitioned into sets based on horizontal and vertical constraints (called Horizontal and Vertical Constraints Model). In order to come up with an expressive hybrid model for direction relations between two-dimensional singlepiece regions (without h...
متن کاملReasoning Mechanism for Cardinal Direction Relations
In the classical Projection-based Model for cardinal directions [6], a two-dimensional Euclidean space relative to an arbitrary single-piece region, a, is partitioned into the following nine tiles: North-West, NW(a); North, N(a); North-East, NE(a); West, W(a); Neutral Zone, O(a);East, E(a); South-West, SW(a); South, S(a); and South-East,SE(a). In our Horizontal and Vertical Constraints Model [9...
متن کاملSpatial Reasoning with Rectangular Cardinal Direction Relations
It is widely accepted that spatial reasoning plays a central role in various artificial intelligence applications. In this paper we study a recent, quite expressive model presented by Skiadopoulos and Koubarakis in [28, 29] for qualitative spatial reasoning with cardinal direction relations. We consider some interesting open problems of this formalism, mainly concerning finding tractable, expre...
متن کاملModeling Cardinal Direction Relations in 3D for Qualitative Spatial Reasoning
Many fundamental geoscience concepts and tasks require advanced spatial knowledge about the topology, orientation, shape, and size of spatial objects. Besides topological and distance relations, cardinal directions also can play a prominent role in the determination of qualitative spatial relations; one of the facets of spatial objects is the determination of relative positioning of objects. In...
متن کاملComposing Cardinal Direction Relations
We study the recent proposal of Goyal and Egenhofer who presented a model for qualitative spatial reasoning about cardinal directions. Our approach is formal and complements the presentation of Goyal and Egenhofer. We focus our efforts on the composition operator for two cardinal direction relations. We consider two interpretations of the composition operator: consistency-based and existential ...
