Publishing deep web geographic data

摘要: This article introduces a design process, called W-RayS, to describe Deep Web geographic data and publish the descriptions both on of Data Surface Web. The also outlines toolkit that supports process discusses an experiment in which was used stored large map server. Briefly, vector format, designer should first specify views over underlying database capture basic characteristics objects their topological relationships represented data. same idea is applied raster data, but using gazetteer or any other covers area as Then, view definitions RDF schema, following Linked principles. are therefore formalized sets triples synthesized from conventional To Data, may decide materialize store them repository create SPARQL endpoint access demand. Web, W-RayS offers tools transform natural language sentences, organized static pages with embedded RDFa. inclusion RDFa preserves structure allows more specific queries, processed by engines analyze
