Approximate spatiotemporal relations between indeterminate evolving regions
Lei Bao, Xiaolin Qin · 2005
Temporal and spatial reasoning are two important parts of artificial intelligence and they have important applications in the fields of GIS (geographic information system), spatiotemporal database, CAD/CAM etc. The development of temporal reasoning and spatial reasoning includes three aspects: ontology, representation model and reasoning methods. This paper checks the correspondence between spatiotemporal relations and the 3D topological relations and presents a relation analysis model for indeterminate evolving 2D regions. It extends 2D egg/yolk model to the third dimension that can describe the approximate topological relations for indeterminate evolving regions. The result is a collection of relation clusters that have different spatiotemporal nature.
