I guess you are looking for SPARQL CONSTRUCT statement.
Reference: http://www.w3.org/TR/rdf-sparql-query/#construct
This gives you the possibility to get "personalised ontologies" as result
(= whole rdf statements).
With SELECT in contrast you always get results of tables (in your query
it's a table with one column).
Here two examples:
CONSTRUCT {<http://dbpedia.org/resource/Presidency_of_Barack_Obama> ?prop
category:Presidency_of_Barack_Obama}
WHERE {<http://dbpedia.org/resource/Presidency_of_Barack_Obama> ?prop
category:Presidency_of_Barack_Obama}
CONSTRUCT {?s ?prop category:Presidency_of_Barack_Obama. ?s
<http://myProperty> "I like it".}
WHERE {?s ?prop category:Presidency_of_Barack_Obama}
With the Sparql Endpoint you can even choose a desired result format (at
http://dbpedia.org/sparql drop down box called "Format Results As"), e.g.
"RDF/XML". Jena should be able to import "RDF/XML" serialized strings.
