Presentation Abstract

Ontologies are models that capture meaning in a machine-readable form. If I told you my parents had three boys, Jim, Daniel, and me, you would know Jim and Daniel were my brothers, even though I didn’t tell you that. With an ontology, you can easily define family relationships, so the computer can infer the unstated fact they are my brothers just like you, a human, can. A traditional data structure would require several joins. A graph database stores the schema and data together, pre-joined in packets called triples, i.e. George isParentOf Mark, Mary isParentOf Jim. The graph database can then be directly queried (with SPARQL) to retrieve the stated and infer the unstated data. But here’s the thing: the ontology creates the mathematical precision to know, not just guess, at the unknown. This IS the next disruptive technology, and you should invest the time to at least understand it!

  • Ontologies model meaning with mathematical precision
  • Graph databases pre-join data under management
  • Ontology-driven data management can accurately infer data that isn’t even there
  • Data can be integrated in place by its meaning rather than table and column names

Come find out how ontology-driven systems will replace our current brittle environments.
