Abstract: This paper builds an Ontology-based Geographic Information Inquiry System OGIIS. At first, GeoOntology Building Algorithm GOBA creates the geographic ontology instance according to the reference ontology. Then, indexes are build and inference are done on these geographic ontology instance. Through reasoning and semantic description, OGIIS can perform precisely and intelligently.

摘要： 本文建立了一个基于地理空间语义网的地理信息查询系统OGIIS(Ontology-based Geographic Information Inquiry System)。通过对异构数据信息进行语义推理和索引，并用地理本体实例生成算法GOBA(GeoOntology Building Algorithm)建立地理本体实例，OGIIS可以极大提高对地理空间语义网上的异构数据信息检索和查询的智能性和准确度。
