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.
