The Virtuoso Sponger (or simply, “the Sponger”) module remains one of the most powerful aspects of our Virtuoso platform, with regards to Knowledge Graph generation and management.

Here is a presentation that demonstrates how the Sponger can be used to progressively create and enhance Knowledge Graphs, with live demo links.

• A quick demonstration of combining SPARQL, SQL, and Cypher by:

  • Using a federated SPARQL query (SPARQL-FED) from OpenLink Virtuoso to mesh data about a specific entity that exists in the DBpedia and Wikidata knowledge graphs

  • Calling a SPARQL-within-SQL (SPASQL) query to return tabular relations in Neo4j, via JDBC

  • Forward Chaining RDF triples to a property graph using Cypher, and visualizing the results

• SPARQL plays nicely with the Small Data theme due to the REST-ful nature of its HTTP-based wire-protocol. Fundamentally, each query solution page is also a REST-ful template.

• Our live GeoSPARQL instance provides a rich GeoSpatial Knowledge Graph that includes data sourced from Natural Earth Shape Files.
