| 摘要: |
| 在分析空间信息服务特点的基础上，对Web服务本体语言(OWL-S)进行扩展，使其可以准确地描述空间信息服务。提出了基于语义的空间信息Web服务“三阶段”匹配方法，实现空间信息服务发现，分别针对基本信息、功能描述、服务质量对服务进行匹配，并根据用户的偏好对服务进行优化排序。实验表明，基于此匹配方法的空间信息服务查准率和查全率明显高于常规的基于关键字的服务匹配方法。 |

| Abstract: |
| Basing on the analysis of geospatial information services, this paper expands Ontology Web Language for Services(OWL-S) so that it can accurately describe geospatial information services. A "three stages" matching method of geospatial information web services based on semantic matching is proposed using these expansions. This method matches geospatial information Web services in basic information, function description and quality of service, it also sorts and optimizes services by user preferences. Experiment results show that the precision and recall of discovery for geospatial information Web services based on semantic matching using the proposed method are higher than that adopting conventional service matching methods based on keywords. |
