Transcript

1. Practical Ontology Morteza Ansarinia
2. Outline • Introduction • Tools • NeON Toolkit • Protégé • Basics • Visualization • Inference • Plugins • Examples • Representation • Problem Solving
3. Introduction •What is an ontology? •Where do I start?
4. Knowledge as Graph Data
7. Statements or Triples < subject, predicate, object > example: < Attack, causedBy, Vulnerability > < Vulnerability, relatedTo, Weakness >
9. Tools - NeON Toolkit
13. Tools - Protégé
14. Tools - Protégé • Free, open source ontology editor and knowledge based framework • is being developed at Stanford University, and University of Manchester • Protégé-owl (3.x and 4.x), Protégé-frame, and WebProtégé
15. Tools - Protégé
16. Protégé as Ontology Designer
