Here we define our objects/questions

%%Question
Who does John love? [oc]
- Mary
- Someone else
- Himself
- No one
What is John doing? <abstract> [oc]
- He isn't doing anything
- He buys a present for Mary
%

The rule:

%%Rule
IF "Who does John love?" = Mary
THEN "What is John doing?" = He buys a present for Mary
ELSE "What is John doing?" = "He isn't doing anything"
%

Dialog to test the knowledge. Answer the first question, the rule will answer the second automatically (red square to reset)

%%QuickInterview

Shows the currently derived fact:

%%ShowSolutions 
  @show_abstractions: true

Here we have the markup to define and compile the knowledge. You can download/export it here (tools in the top right corner):

%%KnowledgeBase

!!Ontology demo

We define our ontology:

%%Turtle
demo:Person a rdfs:Class.
demo:John a demo:Person.
demo:Mary a demo:Person.

demo:loves a rdf:Property.
demo:buysPresent a rdf:Property.

demo:loves owl:sameAs demo:buysPresent.

demo:John demo:loves demo:Mary.
%

Now we query that ontology...

A query do see who loves whom:

%%Sparql
SELECT * WHERE {
	?Person1 demo:loves ?Person2
}
@showQuery: true
%

A query do see who buys a present for whom:

%%Sparql
SELECT * WHERE {
	?Person1 demo:buysPresent ?Person2
}
@showQuery: true
%

%%SparqlVisualization
SELECT ?x ?y ?z WHERE {
	?x ?y ?z
	FILTER (STRSTARTS(STR(?x), "http://example.org")) .
	FILTER (STRSTARTS(STR(?y), "http://example.org") || ?y = rdf:type) .
}
%

Here we have again a markup to compile the ontology. You can download/export it here (tools in the top right corner):

%%Ontology
Demo ontology
@ruleset: OWL_HORST_OPTIMIZED
%

%%Namespace 
  demo http://example.org

Some technical stuff: We define a separate package for all the knowledge on this page, so it is separate from all the other knowledge on d3web.de
