After running the Script,Go to the Results window,there u 
can find the Description of Smart Identification for which 
Object QTP has used.

If object is found using smart identification mechanism the
object is displayed like hat symbol in Test results if any
object are displayed with hat symbol in Test results then u
can say that the object is identified with smart
identification mechanism

Hi,

Generally you can see it in Test Results. In Test results
once you click on the object, it will show you what
properties it used and what properties it ignored to
identify the objects.

Make sure smart identification is enabled to that object
class in object identification. If QTP unable to identify
the object with general identification, then it goes for
Smart Identification.

Thanks,
Uday.
