That doesn't answer my question. Can you try to compare the same queries please?
Moreover what's missing: 1. sample code 2. sample data 3. sample output > The queries are different because in Protege I retrieve only questions and > their complexity number while in Jena I get questions, answers, choices, > scores and its complexity order. > > Regards > > On Fri, Feb 3, 2017 at 6:36 PM, Sidra shah <[email protected]> wrote: > >> Thank you Lorenz, 1,2,3,4,5 are resources and it has URIs.
