基于Ontology的网络地理服务描述与发现

Geo Web Services Description and Discovery Based on Ontology

摘要: 针对目前Web服务的行业标准中服务描述和发现方法的不足,提出了一种基于Ontology的网络地理信息服务描述和发现方法。其核心思想是采用"概念层应用层"两个层次来描述地理信息服务,将服务发布后,通过对服务描述中输入输出等参数和用户需求中功能描述的测度来判断服务与用户需求的匹配程度,从而进行服务发现。

Abstract: This paper proposes an approach to Geo Web Services description and discovery based on Ontology, which employs Ontology to advertise Geo Web Services and uses them for semantics-based discovery of relevant Geo Web Services.
