地理本体空间关系表达模型研究

Research on the Representation Model of Spatial Relation of Geographic Ontology

地理本体是表达地理概念及其之间关系的有效手段,地理本体的空间关系也是其区别于一般本体最重要的特征。本文探析了地理本体的构建方法,将地理本体空间关系分为拓扑关系、方位关系、距离关系和相似关系,重点研究了地理本体的拓扑关系和方位关系的空间表达模型,对拓扑关系进行梳理归纳,总结出8种互斥并完备的空间关系;利用锥形模型对方位关系进行描述,最后利用OWL语言对两种关系进行了推理表达。

Geographical ontology is an effective means to express the concept and the relationship between them, and the spatial rela- tionship of the geographic ontology is also different from the most important feature of general ontology. Thisarticle of the geographic on- tology construction method, the geographical spatial ontology is divided into the relationship between the topological relations, direction relations, between the similar relationships and, focus on the space of topological relations and direction relations between gerontology expression model, the topological relationships to undertake summing up, Summed up the eight kinds of mutually exclusive and com- plete spatial relations ; cone model using their relationships are described. Finally, the OWL language of two types of relationships be- tween the reasoning expressions.
