This PowerPoint presentation uses the famous Wine Ontology example to cover ontology development basics. It answers the question, "What is an ontology and why do we need one?" It includes a step-by-step guide to ontology development and covers advanced issues in knowledge modeling. Uses the open-source tool Protege, with several plugins and applications.
