Building An OWL Ontology: Toxicological Endpoints Ontology Example

Value Partitions can be created to refine our class descriptions, forexample, we will create a Value Partitions called Severity Values Creating a ValuePartitionin OWL consists of several steps:Create sublasses:

Make the subclasses disjoint. An individualcannot be a member of more than one of them.

Create a functional property hasSeverityValue

Make a Severity Values as an Union of all subclasses

4

Building An OWL Ontology: Toxicological Endpoints Ontology Example Disjoint classes: An individual cannot be a member of more than one of them.

Severity Values is covered by subclasses

5Building An OWL Ontology: Toxicological Endpoints Ontology Example OWL Properties represent relationships between two objects.Object properties: link object to objectOWL PropertiesInverse PropertiesEach object property may have a corresponding inverse property.If some property links individual a to individual b, then its inverse property will link individual b to individual a.
