Hi Adeed,
I see sameKEGG as an objectProperty and not as a class. The rule should be
something like:
(?x ex:sameKEGG_p ?y) <-
(?x ddids:x-kegg.pathway ?z),
(?y ddids:x-kegg.pathway ?z),
notEqual(?x, ?y).
But you can get all the subjects that have others with a same value under
a class with:
(?x rdf:type ex:sameKEGG_c) <-
(?x ex:sameKEGG_p ?y).
