Please make sure that the file explicitly asserts all rdfs:subClassOf triples.
When you open files in TBC, the system will add "trivial" inferences to make
sure that each named class has at least one named superclass. These are then
inferred triples, which would not be available by default if your file is
loaded through SPARQLMotion. Also, you may want to import the system triples to
get the same environment like in TBC.
In your query below I don't understand the use of ?arg2. Furthermore, the use
of the rather ugly (legacy) function smf:countResults could be replaced with a
SPIN function such as spl:objectCount.
