in the TargetPhrase class, there is a method
GetContainer()
which points to the phrase-table that a particular rule comes from. You
can use this.

Hi,

when you call the decoder with the option "-tt" then you get for
each phrase pairs a list of all feature scores. You can use this
to track down which phrase table was used for each phrase
translation.
