一种新的地理本体构建方法研究

摘要

地理本体区别于其他领域本体的显著特征是具有空间拓扑特征.目前,还没有比较完善的地理本体实例描述方法及地理本体构建方法,本文在本体实例构建方法的基础上研究地理本体实例描述方法,通过物质成分、物理形态、空间分布、功能、等级等5方面属性信息及拓扑关系、方向关系、位置关系等3方面空间拓扑特征描述地理本体实例,并以黄河为例,利用OWL语言对其进行形式化描述;研究了基于实例描述方法的地理本体构建方法.%The distinguishing feature of the ontology is that it has the feature of spatial topology.At present,no geographic ontology instance perfect description method and geographic ontology construction method,description method of geographic ontology based on ontology construction method,through the three aspects of material composition and physical tropology,spatial distribution,function,level five aspects of attribute information and topology relation,direction relation and the relationship between the position of spatial topological description of the features of the geographic ontology instance,taking the Yellow River as an example,gives a formal description of the use of OWL language;study the method of establishing geographic ontology description method based on examples.
