How do you use path in a rule? My attempt doesn't work

The rules at the bottom of the attached file are intended to derive per:languagesSpoken from a path, but apparently there is something wrong with the path expression.  Can someone point out the problem.

 <<languagesSpoken.n3>> 
Command line:

python ..\cwm.py languagesSpoken.n3  --think
