Neo4j GraphTour New YorkOntologies and Knowledge Graphs
The document discusses the use of ontologies and knowledge graphs within Neo4j, highlighting interoperability, inferencing, and the role of W3C standards. It provides examples of popular ontologies like FIBO and schema.org and demonstrates how to integrate, publish, and infer semantics using Neo4j and the Neosemantics plugin. The concluding sentiment emphasizes that RDF and its standards are merely tools, and emphasizes a pragmatic approach to semantics.
