hi, this is a bug tracker. please join our mailing list https://www.freelists.org/list/dl-learner-discussion . You should be able to use any Named Individual as positive example, so this is the first thing I would check
from dl-learner.
As a comment, most algorithm of the DL-Learner learn descriptions of a set of individuals. As long as the objects of the triples are individuals, it will work. For literals indeed it doesn't make sense or better said, we don't have nay algorithm so far given that describing a set of literals is somewhat limited in OWL.
I saw that you used data from DBpedia, if so, don't forget to add the DBpedia ontology triples as well, otherwise the OWL API parser isn't able to determine the type of the properties and each property is treated as annotation property, thus, DL-Learner won't consider them as candidates to be used.
But let's continue on the mailing list...
