Where do spatial context-models end and where do ontologies start ? A proposal of a combined approach

on the state of the physical world along with other information representing context. This requires context management , i.e., the efficient management of context information and feasible context representations in order to allow reasoning. This paper discusses two common approaches, spatial context models and contextual ontologies, and argues for a combined approach providing the efficiency of context management through context models combined with the semantic expressiveness of ontologies.
