Although spatial relations are essential for the anatomy domain, spatial reasoning is only weakly supported by medical knowledge representation systems. To remedy this shortcoming we express spatial relations that can intuitively be applied to anatomical objects (such as 'disconnected', 'externally connected', 'partial overlap' and 'proper part') within the formal framework of description logics. A special encoding of concept descriptions (in terms of SEP triplets) allows us to emulate spatial reasoning by classification-based reasoning.
尽管空间关系对于解剖学领域至关重要,但医学知识表示系统对空间推理的支持却很薄弱。为弥补这一缺陷,我们在描述逻辑的形式框架内表达了一些可直观应用于解剖对象的空间关系(如“分离”“外部连接”“部分重叠”和“真部分”)。概念描述的一种特殊编码(根据SEP三元组)使我们能够通过基于分类的推理来模拟空间推理。
