Ontology: Pizza.owl using Protégé
Practice building pizza.owl ontology using Protege modeling tool, base on Michael DeBillis’ great guide.
Here you can find the post by Michael in his site; and the introduction of the guide.

Ontologies inside Semantics Concept
Source from post of Malcolm Chirholm Ph.D.
| Terms | Description |
|---|---|
| Ontologies | Each is a “view” of the business world (and business information) that is required to meet a specific business need |
| Business Rules | Atomic units of logic that govern behavior of concepts and relationships |
| Relationships | Other business relationships outside taxonomies and hierarchies |
| Hierarchies | How individual things (instances) are associated at multiple levels for specific businees needs |
| Taxonimies | The relationships of general with specific concepts |
| Definitions | Descriptions of the concepts identified by the terms |
| Terms | The specialized terms used in the business, with homonyms, synonyms, and universes of discourse identified |
Learn Ontologies from pizza.owl
Thanks for Michael DeBellis’s great tutorial on pizza.owl, which is helping to understand the key concepts of ontology and also a way of building practices.
This repository is tracking my hands-on modeling the pizza.owl in step-by-step manner, and you can find the snapshot ontology model files in every step so that you can start your practice from any point.
Why Protégé?
Check Protege Website, you can find below statements:
Protégé’s plug-in architecture can be adapted to build both simple and complex ontology-based applications. Developers can integrate the output of Protégé with rule systems or other problem solvers to construct a wide range of intelligent systems. Most important, the Stanford team and the vast Protégé community are here to help.
I’m using Protégé to learn pizza.owl and also practice the modeling skill here.
Some reference quick link about Protégé:
- WebProtégé
- Download Windows Version 5.6.1, also have Java package for platform independent installating.
- Protégé wiki
- Protégé in Github, from here you can get latest version
