摘要
时空地理本体模型是一套描述地理时空知识的形式化说明规范,是构建时空地理本体实例的基础和参考。本文基于GML规范及时空推理理论提出了一种时空地理本体模型的框架,并详细阐述了其组成:要素模型、几何模型、空间关系模型、时态模型中类的关系和所涉及到的属性定义,并基于该本体模型给出了应用实例——行政区划本体设计和构建方法。文中所提出的时空地理本体模型,对开展面向不同应用的地理本体实例的构建和共享研究具有一定参考意义。
Geo-ontology is the key of geographic knowledge existed in human brain being rebuilt in computer. The geo-ontology has important significance to improve and support formalized expression of geographic knowledge in computer. The model of spatio-temporal geo-ontology is a set of specification of formalized instruction describing ge- ographic spatio-temporal characteristics. And it is the reference and basis for building spatio-temporal geo-ontology. The framework of spatio-temporal geo-ontology model based Geography Markup Language （GML） and the theory of spatio-temporal reasoning is proposed. The method of building spatio-temporal geo-ontology model is studied. The spatial ontology model, which consists of feature model, geometry model and spatial relationship model, is imple- mented by OWL language. And the temporal model, which consists of time instant and time period, is illustrated as well. The feature model is the core of spatio-temporal geo-ontology; it is connected with geometry model, temporal model, and spatial relationship model by object property in OWL. An applied example＂ the ontology of administra- tive regionalization＂ is given based on the model in the end. In the section, region ontology based Class Feature in spatio-temporal geo-ontology is built and it can be the ancestor of all other kinds of geographic unit. Administrative region ontology inherits the region ontology and extends it. The spatio-temporal characteristics and administrative level characteristics of administrative region are demonstrated based on some object properties defined in the model of spatio-temporal geo-ontology. It is of instructive significance to build and share the instances of geo-ontology for different applied studies based on the model of geographic spatio-temporal ontology.
