Export experiments in Corese

This document summarizes the export experiments conducted with the Corese RDF engine during the Interoperability Working Days held on October 10-11, 2005. Corese, developed by Olivier Corby, is an RDF engine based on conceptual graphs that supports RDF, RDFS, and some OWL Lite features. The experiment involved executing a benchmark suite, loading ontologies, performing SPARQL queries, and saving the results. Corese's unique features, including approximate search and a rule-based inference engine, show its application in various projects at INRIA.

  2. Index • Corese at a glance • Execution of the benchmark suite

  3. Corese • Corese is an RDF engine based on Conceptual Graphs. • It implements RDF, RDFS, some statements from OWL Lite and the query pattern part of SPARQL. The query language integrates additional features such as approximate search, group, count, graph path.  • Corese also integrates an RDF Rule Language based on the CG Rule model. The inference rule engine works in forward chaining. • Corese is embedded in a Semantic Web Server (based on Tomcat). It has been applied in more than 10 applications at the INRIA and is available for downloaded.  • Corese data structures are based on the notio CG platform and uses the ARP RDF parser from HP.

  4. Index • Corese at a glance • Execution of the benchmark suite

  5. Execution of the benchmark suite No modifications were needed in the tool for performing the experimentation. • Load the O'Comma ontology and an additional toy ontology to cover all the benchmarks. • Write a set of sparql queries. • Execute the queries againts the ontology. • Save the results in separate files.
