    • 摘要: 定性空间推理是定性推理和空间推理的重要组成部分 .拓扑和形状是定性空间推理研究的关键问题 .针对定性空间推理已有一般框架存在的问题 ,提出了定性空间推理的分层递阶框架 ,并结合拓扑和形状方面的定性空间推理研究工作阐述了所提出的框架的有效性和合理性 .最后总结了分层递阶框架的要点并提出了基于该框架的进一步研究工作 .

       

      Abstract: Qualitative spatial reasoning (QSR) is an important component of qualitative reasoning and spatial reasoning. Topology and shape are key problems in QSR research.In this paper, a generic hierarchical framework for qualitative spatial reasoning is first proposed to improve and develop the existing frameworks of qualitative spatial reasoning. Then some results about topology and shape researches in QSR are provided to demonstrate the validity and rationality of the hierarchical framework. Finally the gist and the open problems of the hierarchical framework are outlined.
