OWL: 

OWL Web Ontology Language W3C Recommendation 10 February 2004 http://www.w3.org/TR/2004/Rec-owl-guide-20040210/ http://www.w3.org/TR/2004/Rec-owl-ref-20040210/ http://www.w3.org/TR/2004/Rec-webont-req-20040210/

OWL: 

OWL “…is intended to provide a language that can be used to describe the classes and relations between them that are inherent in Web documents and applications.”

OWL: 

OWL Formalize a domain by defining Classes Properties of those classes Define individuals Assert properties about them Reason about these Classes and Individuals

Ontology: 

Ontology From philosophy – the science of describing Kinds of entities in the world How they are related

OWL Ontology: 

OWL Ontology May include Classes Properties Instances Capture semantics Multiple, distributed, related ontology schema Normative OWL exchange syntax RDF/XML Resource Description Framework/Extensible Markup Language

Taxonomy, Thesaurus, & Ontology: 

Taxonomy, Thesaurus, & Ontology Taxonomies and thesauri are not ontologies They are entities or “conceptualizations” Ontology – science of describing kinds of entities For thesauri and taxonomies “a specification of a conceptualization”

Taxonomy, Thesaurus, & Ontology: 

Taxonomy, Thesaurus, & Ontology OWL output Provides semantic meaning to these kinds of entities or conceptualizations Web resource Accessible to automated processes
