Unit 8 Formative Activity

Task

Work through Chapter 4 of Debellis (2021) A Practical Guide to Building OWL Ontologies Using Protégé 5.5 and Plugins. Create an ontology following Exercises 1-7.

My University Ontology

Domain: Higher Education System

Classes Created:

• University
• Department
• Course
• Student
• Professor
• Degree

Object Properties:

• hasStudent (University → Student)
• belongsToDepartment (Professor → Department)
• teaches (Professor → Course)
• enrolledIn (Student → Course)

Data Properties:

• hasName (String)
• hasID (Integer)
• hasGPA (Float)
• yearEstablished (Integer)

Key Insights: Following the step-by-step exercises made the ontology development process clear. Setting up class hierarchies first, then properties, then instances creates a logical flow. The reasoner validation in Exercise 6 caught several inconsistencies I missed manually.
