摘要：

为了实现地理语义数据的快速有效的空间查询，通过分析传统RDF索引方法和空间索引方法的不足，结合两者提出一种基于空间四元组（GeoQuad）的地理语义空间索引构建方法，并基本该方法利用Jena和ARQ实现基于SPARQL语法的地理语义空间查询。实验表明，方法高效可行，不仅能够快速定位空间RDF节点，而且能够快速进行RDF空间查询并返回RDF结果。

关键词: 空间四元组, 地理语义空间索引, SPARQL, 地理语义空间查询

Abstract:

In order to quickly and efficiently query Geo Semantic data, by analyzing the lack of traditional RDF Index and Spatial Index method, this paper proposes a construction method of Geo Semantic Spatial Index based on GeoQuad, and realizes the Geo SPARQL Spatial Query by this method based on Jena and ARQ. Experiments show that this method is feasible and efficient, It is not only able to locate the spatial RDF nodes quickly, and can quickly spatial query Geo RDF data, returning RDF results.
