摘要
本文建立了地理数据类型本体和地理服务类型本体,提出了基于OWL-S地理理信息服务发现方法。其核心思想是用OWL-S进行服务描述和发布,通过对服务语义描述中的输入、输出、服务分类进行分级匹配实现服务的自动发现。
This paper designed geo_DataType ontology and geo_ServiceType ontology.An approach for geoSpatial Web service discovery was proposed,in which geospatial Web services are described and advertised by OWL-S,and then a matching degree was ranked according to the input/output and service category for requested and advertised service descriptions to implement Web services discovered automatically.
