Abstract

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 models 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 the 2D Egg/Yolk model into 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 natures.
