基于规则知识的空间推理研究

在一般空间推理的基础上,提出了空间推理扩展,即基于规则知识的空间推理。该方法结合了人工智能的基本原理,继承并发展了空间推理的方法学,其推理过程建立在空间知识与模型集成的基础上,以规则知识为推理控制,因而更符合实际,具有更大的灵活性。实例验证了本方法的正确性。

Spatial Reasoning Based on Rule-based Knowledge

Spatial reasoning,as an effective tool for GIS spatial analysis,has been attracting hot focuses from researches.The general method on spatial reasoning only takes spatial relations contained in spatial data into account,but this is not complete.Some requirements,which are also called general knowledge,can be regarded as a kind of special knowledge that should be met in spatial reasoning.In this paper,the method,or spatial reasoning of rule_based knowledge,for integrating spatial relations and general knowledge is discussed.This method inherits and extends the current spatial reasoning method to include a complete knowledge disposal system.Rule_based knowledge representation and object_oriented knowledge representation methods are used to express spatial and general knowledge.Knowledge and models for spatial reasoning are integrated together to complete spatial reasoning.Lastly,an case study on selecting monitor points for a hierarchy administrative region is detailed.
