基于CSW的个性化地理空间资源发现研究

Research on the Personalized Discovery of Geospatial Resources Based on CSW

摘要: 为解决目前空间地理信息检索中存在的主要问题，增强CSW对地理资源的检索能力，将本体技术与偏好查询理论引入CSW，采用适应偏好查询的地理资源元数据模型，提出了一个个性化地理空间资源发现系统，设计基于语义的地理资源发现方法，并搭建了原型系统。实例证明本文提出的方法能够有效检索出优质的地理空间服务资源。

Abstract: In order to solve the main problems existing in current space geographic information retrieval, and enhance the capacity of CSW on geographical resources retrieval, this paper combined ontology query technology system and the preference theory into CSW, explored the geographic resources metadata model that adapts to preference queries, proposed a personalized geospatial resource discovery system, designed the geographic resource discovery method based on semantic technology, then set up a prototype system. The examples prove that the proposed method can effectively retrieve the high quality geospatial service resources.
