I have instances from GraduateCourses and UnderGradCourses classes:

Computer Vision Databases

?x rdf:type std:GradCourses ?y rdf:type
std:UnderGradCourses
Now ?x and ?y contains courses with "Semantic Web and Network security"
common in both.
Can we do some arithmetic or comparison inside Jena rules which will
query/answer us the courses which are common in both?
(?x rdf:type std:GradCourses) (?x rdf:type std:UnderGradCourses)
-> (?x rdf:type std:BothGradAndUnderGradCourses)
or whatever you want to call the intersection class.
This sort of intersection checking is possible in rules, in OWL or in
SPARQL queries. Just depends what you want to do.
