Complex Operational and Organizational Problems

Topic: Ontologies

Dr. Dean S. Hartley III

Ontologies are like taxonomies on steroids.  Taxonomies are tree shaped networks.  Each node has one parent and several children nodes.  In an ontology, each node may have several parents as well as several children nodes.  In addition, ontologies may have more than one type of relation between nodes (e.g., "is-a" [a pie is-a dessert] and "part-of" [a crust is part-of a pie]). Sometimes context diagrams, such as the one below, help to understand the relationships among parts of an ontology.
