Representation of spatial information for the Semantic Web often involves qualitative defined information (i.e., information described using natural language terms such as “North”), since precise arithmetic descriptions using coordinates and angles are not always available. A basic aspect of spatial information is directional relations, thus embedding directional spatial relations into ontologies along with their semantics and reasoning rules is an important practical issue. This work proposes a new representation for directional spatial information in ontologies by means of OWL properties and reasoning rules in SWRL embedded into the ontology. The proposed representation is based on the decomposition of cone shaped directional relations (CSD-9) offering a more compact representation and improved reasoning performance over existing approaches. A 3D representation is proposed as well and both 2D and 3D representations and reasoning are evaluated.
