This requires a full characterization of the semantics of relations such as adjacent, included, overlapping, etc. Nevertheless, ontologies are not expressive enough to directly support widely-use spatial or topological theories, such as the Region Connection Calculus (RCC). In addition, these properties must be properly instantiated in the ontology, which may require expensive calculations. This paper presents a practical approach to represent and reason with topological properties in ontology-based systems, as well as some optimization techniques that have been applied in a video-based Information Fusion application.6application/pdfeng© 2011 IEEEInformation FusionOntology-based SystemsSpatial PropertiesTopological Reasoningconference paperInformática10.1109/ISDA.2011.6121844open access13291334Proceedings of the 2011 11th International Conference on Intelligent Systems Design and ApplicationsCC/0000017382
