Here we define our objects/questions

%%Question
Who does John hate? [oc]
- 玛丽
- 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 hate?" = 玛丽
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)

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

!!Ontology demo

We define our ontology:

%%Turtle
demo:Person a rdfs:Class.
demo:Student rdfs:subClassOf demo:Person.
demo:John a demo:Student.
demo:玛丽 a demo:Student.

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

demo:loves owl:sameAs demo:buysPresent.

demo:John demo:loves demo:玛丽.
%

Now we query that ontology...

A query do see who loves whom:

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

A query do see who buys a present for whom:

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

A visualization of the ontology:

%%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) .
}
%

%%SparqlVisualization
     SELECT ?x ?edge ?z WHERE {
	    ?x ?y ?z . 
	    ?x rdfs:subClassOf si:Person. 
	    ?z rdfs:subClassOf si:Person. 
	    ?x rdfs:subClassOf ?z.
	   
	    FILTER NOT EXISTS { 
	    	?middleObject rdfs:subClassOf si:Person. 
	    	?x rdfs:subClassOf ?middleObject. 
	    	?middleObject rdfs:subClassOf ?z.
	    	FILTER (?middleObject != ?x ).
	    	FILTER (?middleObject != ?z ).
 	    }
 	    FILTER (?x != owl:Nothing).
 	     FILTER (?x != ?z).
	    BIND (" " AS ?edge).

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

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
