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.
General Domain Model#
We first define some classes framing the example domain.
Some (alternative ways) to express negations.
rdfs:range si:Human; rdfs:domain si:Human.
Bart never wants to be a female.
We now insert some characters and things of the Simpsons world.
We can also introduce blank nodes to represent the belongings of Mr. Burns.
Ok, we can test/query the ontology by inserting some SPARQL statements.
Show me all instances of Human and also show their labels.
Use property paths in SPARQL.
Now using a defined PropertyChain
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
Administrative Definitions of the Simpsons Ontology#
