Scope of University Ontology
• university: key player in higher education
• “vital to knowledge-based economies”
(OECD, 2014)
• Useful for developing an e-learning system
• Contributes to Ontology for Educational
Resources
4
Previous University Ontologies I
1. Built with Protégé & OWL
in the context of the Sematic Web
2. As a case study on domain ontology
3. Not based on any upper-level ontology
4. Language/concept-dependent
5
Previous University Ontologies II
• Ex.1 Person
Employee
…
AdministrativeStaff
…
Chair {Professor}
Dean {Professor}
6
Previous University Ontologies III
• Ex.2 Organization
Educational Organization
Department
Institute
Program
ResearchGroup
School
University

Previous University Ontologies IV
• Ex.3 - Non-TeachingFaculty
- Examination
_invigilatedBy_Teaching-Faculty
- Courses
_hasWeeklyBreakup_WeeklyBreakup

Advanced University Ontology
1. Built with Protégé & OWL
in the context of ontological engineering
2. Aims to help develop an e-learning
system
3. Based on an upper-level ontology BFO2
4. Mirrors better a university in reality

An Overview
• 122 terms and 24 types of relations
• 50 terms with definitions and/or
comments
• Exploits instance-level relations in BFO2

4 Key Terms & Their Definitions I
• organization =Def. an object aggregate
whose member parts have roles of specific
types
1. university =Def. an organization whose
member parts are teachers, students,
researchers, assistants, administrators
and a president
18
4 Key Terms & Their Definitions II
2. university_department
=Def. an organization whose member
parts are teachers, students,
researchers, assistants, and
administrators in a specific way
19
4 Key Terms & Their Definitions III
3. university_student =Def.
a person who has the role of being a
university student at some time
• university_student_role =Def.
to learn knowledge
20
4 Key Terms & Their Definitions IV
4. university_course =Def.
a generically dependent continuant
which depends on teachers and
teaching assistants such as it is
concretized by a teaching plan in
their heads
• class (occurrent) / course (continuant)
21
Evaluation
• Single-Inheritance Hierarchy
• Consistency
• Room for improvement in completeness
• Questionable actual accessibility
22
Conclusions & Future Work
• Integrates existing university ontologies
• Reflects better a university in reality
• Expansion (e.g. to management )
• Deployment (e.g. use in a real university)
