Re: [DL-Learner discussion] DL-Learner solution not including object properties

Dear Md Kamruzzaman Sarker, I think you should remove "ex:heinz" from the set of positive examples. Because, according to the ontology, Heinz is a male and nowhere in the ontology it is written that he has a child. You have as positive individuals all the individuals that are male and as negative ones the individuals that belongs to the female class. Therefore as best class expression DL-Learner will find "male". (If you remove Heinz you will notice the "hasChild" property in the list of candidate class expressions) Best Regards, Giuseppe Cota On 02/05/2017 17:33, Sarker, Md Kamruzzaman wrote: > > Hi Lorenz, > > Many thanks for your reply.
