摘要: 针对元数据缺乏语义描述和隐含关系推理能力,用户无法获得匹配度较高的地表覆盖信息并且检索到的相关资源数量较少的问题,本文在传统OGC目录服务中加入本体推理机制提出了地表覆盖语义目录服务,并以国家地理信息元数据标准为原型设计了地表覆盖元数据模型。随后以此为基础构建了地表覆盖元数据本体模型,并使用网络本体语言OWL对其进行形式化表达。最终通过构建地表覆盖语义目录服务,有效提高了地表覆盖资源的查全率和查准率,实现了地表覆盖信息的精准共享。

Abstract: For the lack of semantic description and implicit relational reasoning ability of metadata, users can't obtain the high-matching land cover information and the number of related resources retrieved is small. This paper proposes the land cover semantic catalogue service by adding ontology reasoning mechanism to the OGC catalogue service, and then designs the land cover metadata model based on the national geographic information metadata standard,builds the ontology model of land cover metadata based on it. Then it uses OWL to formalize the ontology model, and implements the semantic catalogue service of surface coverage using Java. Experiments show that the ontology can effectively improve the recall and precision of surface coverage resources.

Key words: land cover, metadata, ontology, service, sharing
