  1. OWL Constructs: Classes Tools---Quick QWL – Create multiple sublasses On the base of LeadscopeToxML schema Building An OWL Ontology: ToxicologicalEndpoints’OntologyExample

  2. OWL Constructs: Create “Organs” SuperClasse containing different subclasses on the base of GoReni Building An OWL Ontology: ToxicologicalEndpoints’OntologyExample

  3. OWL Constructs: Create “Lesions” (Effects ) SuperClasse containing different subclasses on the base of GoReni Building An OWL Ontology: ToxicologicalEndpoints’OntologyExample

  4. Value Partitions can be created to refine our class descriptions, for example, we will create a Value Partitions called ‘Severity Values’ Creating a ValuePartition in OWL consists of several steps: Create sublasses: Make the subclasses disjoint.An individual cannot be a member of more than one of them. Create a functionalpropertyhasSeverityValue Make a SeverityValuesasan Union of allsubclasses Building An OWL Ontology: ToxicologicalEndpoints’OntologyExample

  5. Disjoint classes: An individual cannot be a member of more than one of them. Building An OWL Ontology: ToxicologicalEndpoints’OntologyExample ‘Severity Values’ is covered by subclasses

  6. OWL Properties OWL Properties represent relationships between two objects. Object properties: link object to object Building An OWL Ontology: ToxicologicalEndpoints’OntologyExample InverseProperties Each 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. haspossiblelesions lesions organs Islesionfororgan

  7. Property restrictions In OWL, properties are used to create restrictions. Restrictions are used to restrict the individuals that belong to a class Building An OWL Ontology: ToxicologicalEndpoints’OntologyExample
