摘　　要：为了实现地理语义数据的快速有效的空间查询,在分析和研究传统RDF(resource description framework)数据组织方法和空间索引的基础上,提出地理空间四元组(GeoQuad)模型,并基于该模型构建了地理语义空间索引,最后利用Jena、ARQ和JTS Topology Suite实现了支持语义查询规范-SPARQL的地理语义空间查询。试验表明,方法高效可行,不仅能够快速定位空间RDF节点,而且能够快速进行空间查询并返回RDF结果。In order to query geo semantic data efficiently, based on the analysis of traditional RDF（resource description framework） data organization methods and spatial index methods, Firstly,a geospatial quad data modeI--GeoQuad was proposed, and then ,on the basis of this model a geo semantic spatial index method was constructed. Finally, using tools such as Jena, ARQ and JTS topology suite, a Geo SPARQL spatial query was achieved, which supported semantic query specification--SPARQL. Experiments show that this method is feasible, which is not only able to locate the spatial RDF nodes quickly, but also can quickly spatial query on RDF data by returning the results in the form of RDF node.
