Review • Controlled vocabularies – Term Lists, Hierarchies, Trees, Paradigms, Facets, Folksonomies • Knowledge organization systems – Term Lists, Thesauri, Taxonomies, Ontologies INLS 520 Erik Mitchell

Your ontology should contain multiple classes and instances and be focused on a specific purpose. This assignment includes an implementation of the ontology in Protégé and a brief paper explaining your ontology. • Guidelines • Select a topic of interest and determine the top level (i. e. Basketball, Chocolate, etc). • Define the scope (depth/breadth) and purpose of the ontology. Define specific classes and facets (known as slots in Protégé) that describe those classes. Your ontology should have between 5 -10 classes with multiple (2 -5) slots for each class. Think about the use of hierarchy and multiple inheritance in your ontology. • Summarize your ontology in a short paper (no more than two pages). Outline your ontology and discuss your rationale and key decisions (e. g. scope, purpose, classes and slots, defining relationships) • Implement the ontology in Protégé. Define your classes and instances. Create two queries that illustrate ways in which the data could be retrieved. • Dates & groupwork • Due – November 6 th • Groupwork is acceptable INLS 520 Erik Mitchell </p> </div> <div style="width: auto;" class="description columns twelve"><p><img class="imgdescription" title="RDF • Subject, property, object triples • Transmitted in xml • RDFS extends RDF" src="https://present5.com/presentation/352ef94a52f5ccfd9d6eef34267f1326/image-26.jpg" alt="RDF • Subject, property, object triples • Transmitted in xml • RDFS extends RDF" /> RDF • Subject, property, object triples • Transmitted in xml • RDFS extends RDF with an ontology language – Properties, specialization • OWL – More powerful extension of RDFS – Uses same syntax of RDF INLS 520 Erik Mitchell </p> </div> <div style="width: auto;" class="description columns twelve"><p><img class="imgdescription" title="RDF Model Author Webpage: http: //www. stuff. com “Saki Knafo” (Resource) (Property type) (Value)" src="https://present5.com/presentation/352ef94a52f5ccfd9d6eef34267f1326/image-27.jpg" alt="RDF Model Author Webpage: http: //www. stuff. com “Saki Knafo” (Resource) (Property type) (Value)" /> RDF Model Author Webpage: http: //www. stuff. com “Saki Knafo” (Resource) (Property type) (Value) Subject Predicate Object “The author of the stuff webpage is Saki Knafo” - A literal, a triple, a statement INLS 520 Erik Mitchell </p> </div> <div style="width: auto;" class="description columns twelve"><p><img class="imgdescription" title="How is RDF different?
