Still using the dbpedia Virtuoso browser, http://dbpedia.org/sparql, I applied the last query to a single dbpedia page by specifying the default graph uri as http://dbpedia.org/resource/Joan_Baez. This will show the various ways dbpedia classifies Joan Baez.
Virtuoso SPARQL Query Form
COMPARE TO THE DBPEDIA PAGE FOR JOAN BAEZ
When starting with SPARQL, I often pored over the dbpedia resource file in order to compare it with my SPARQL output to see if I got the SPARQL code right. These results match the entries under rdf:type (the predicate which was abbreviated as a).
Note: I did not specify the Joan Baez human readable page, http://dbpedia.org/page/Joan_Baez, in the Default Graph URI.
Instead, I specified the RDF page, http://dbpedia.org/resource/Joan_Baez" which is designed for SPARQL querying. However, if you point your browser to to resource page, dbpedia will show you the human readable page. The Sparql query engine however can go straight to the underlying RDF.
