General purpose query interfaces to relational databases can expose vast amounts of content to the semantic web. In this paper, the authors discuss Automapper, a tool that automatically generates data source and mapping ontologies using OWL and SWRL. They also describe the use of these ontologies in their semantic distributed query architecture, an implementation for mapping RDF queries to disparate data sources, including SQL-compliant databases, using SPARQL as the query language. This paper covers Automapper functionality that exploits some of the expressiveness of OWL to produce more accurate translations.
