ENTERPRISE KNOWLEDGE
EK’s Definition of Ontology
A defined data model that describes
structured and unstructured information
through:
• entities,
• their properties,
• and the way they relate to one another.
• Ontology is about things, not strings.
• Ontologies model your domain in a
machine and human understandable
format.
• Ontologies provide context.
• Effective ontologies require a deep
understanding of the knowledge domain.
