Pantelis,

Just a hint, use RDF querying to ask for feature values for particular
compound. It should not matter whether nodes are anonymous or not.  I'll
try to add more examples.

One option is
StmtIterator iter =  queryObject.listStatements(new
SimpleSelector(subject,predicate,object);

Best regards,
Nina
