Hi June,

your prefix declaration in the config file is wrong. You have to set the
prefixes which are used in the ontology, and not a path to the file. For
the positive examples the prefix must be
http://www.Department0.University0.edu/ . For the negative examples this
is much more difficult because it seems that the namespace of the
publications depends on the professor. For example
http://www.Department0.University0.edu/AssociateProfessor1/Publication8.
It seems to me that you added all instances which are not positive as
negative examples? You could also use a learning algorithm which only
needs the positive examples.

DL-Learner provides an option for default negation.

Lorenz
