A semantic wrapper of deep web data source based on RDF view
One of the tasks for semantic web is to integrate large amounts of data in current Deep Web data sources into machine-understandable RDF data model to form a "web of data". Currently, mediator/wrapper approach is commonly used in the RDF-based data integration to describe the data model of heterogeneous data sources as intermediate RDF model by RDF wrapper. This paper describes a wrapper of Deep Web data source uses RDF View. The wrapper supports the SPARQL-to-SQL query rewriting and wrapping the SQL query results as RDF data.
