You have posted some good questions.  If you wish, please post the 
responses and your paper - I would be very interested.

:  1) Which inference-techniques does the system support?
:     (forward/backward chaining, top-down/bottom-up inference)
:  
:  2) Does the system offer multiple answers/conclusions?
:     (Is it possible to obtain more than one anwser/conslusion (in a single
:      session) given some evidence?)

:  3) How large is the system? 
:     (How many rules/relations does the system consist of?)

:  4) How fast is the system?
:     (How long does it take to run an ordinary session?)

: If you decide to help me, and if your information is of use to me,
: I'll make sure that you'll be credited in the project-report.

: Thank you for your time.

: PS: If you have the source-code of a system, and if it isn't protected
: by law in any way, please let me know as well.
