【摘要】 论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-basedGeographicInformationInquirySystem)。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(GeoOntologyBuildingAlgo-rithm)建立地理本体实例,OGIIS可以极大地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。更多还原

【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 built and inference are done on these geographic ontology instance.Through reasoning and semantic description,OGIIS can perform precisely and intelligently.更多还原
