[DL-Learner discussion] two questions with dllearner, wait for help, thanks

[June <zhu...@gm...>]

Hi list,

I am trying to use DLLearner now, and the version I am using is 1.0 beta 
2, the latest release on the dllearner webpage. But I encountered some 
exceptions. Could anyone here help me to solve this problem? What might 
be the problems with the conf file? Attached are the conf file I am 
using, the error log, and the ontology.

Another question I'd like to know is that in DLLearner is it the case 
that when an instance can not be known (by reasoning maybe) to be an 
individual of a concept, it is not then.

Many thanks!

Best regards,

June

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
