Generating Rewrite Rules by Browsing RDF Data

In this paper we show how path queries in the Wilbur query engine can be augmented via the use of a simple rule system. This system can substitute atomic query expressions with complex queries, effectively rewriting queries. We demonstrate that this approach can be used for simple reasoning in the context of RDF(S). We further present a tool that allows the user to create complex queries merely by browsing an RDF graph, and by virtue of naming the automatically generated queries can create rules for the rule system. These rules appear in the system as "virtual" RDF properties, and enable the user to interactively customize how RDF data is presented
