The Simpsons - An example Ontology for tutorial purposes#
The Simpsons is a popular comic televisions series. A comprehensive overview (in german) is Simpsonspedia
.
This page shows, how we implement the simpsons ontology in KnowWE.
Also, please check out our visualization docs, which are based on the ontology defined here: Doc SparqlVisualization, Doc ConceptVisualization

Sample Queries#
Ok, we can test/query the ontology by inserting some SPARQL statements.
Simple start#
Show me all instances of Human and also show their labels.
Barts Grand-Pa#
Use property paths in SPARQL.
Now using a defined PropertyChain
Optional belongings#
We also can add optional patterns into the query. Show all humans and their (optional) belongings.
UNION: All names of humans and animals#
Expected Compentency Questions: Intersecting Properties#
The family father: A father that is also a husband
Hierarchical Table#
Administrative Definitions of the Simpsons Ontology#
This wiki article belongs to the simpsons package.
We define the ontology using all articles of the simpsons package. Let's use the namespace si for the resources.
