中文简介:
空间推理的核心问题是找到一组适当的计算关系。本文提出人类使用三种基本的定性关系来表示二维区域之间的拓扑关系:包含,交叉和重叠。我们展示了如何使用中等水平感知模型从草绘输入计算这些关系。试点实验的结果表明,这三种关系足以解释人们对四种英语空间术语(“交叉”,“重叠”,“连接到”和“包含”)的判断,尽管三者的组合通常是每个学期都需要。
课程简介: A core problem in spatial reasoning is finding an appropriate set of relationships to compute. This paper proposes that humans represent topological relationships between 2D regions using three basic, qualitative relations: contains, intersects, and overlaps-with. We show how these relations can be computed from sketched inputs using a model of mid-level perception. Results from a pilot experiment indicate that these three relationships suffice to explain people‟s judgments on four English spatial terms (“intersects”, “overlaps”, “connects to”, and “contains”), although a combination of the three is generally required for each term.
关 键 词: 空间推理; 拓扑关系; 计算关系
