How to Stay Ontop of Your Data: Databases, Ontologies and More

Revised Selected Papers of ESWC Satellite Events. Volume 9341 of Lecture Notes in Computer Science. 2015.

Ontop is an Ontology Based Data Access system allowing users to access a relational database through a conceptual layer provided by an ontology. In this demo, we use the recently developed NPD benchmark (+4 billion triples) to demonstrate the features of Ontop. First we use Ontop as a SPARQL end-point to load the ontology and mappings, and answer SPARQL queries. Then, we will show how to use Ontop to check inconsistencies and exploit SWRL ontologies.
