Thank You German and Hie for your reply
It is just from what I noticed that the transition score of a hypothesis is
it is score minus the score of the hypothesis stated in the "Back"
field.(am I right? )

Also I tried multiplying the core scores with the weights from moses.ini
(and then sum over the multiplication), but I did not get the the right
score indicated by the hypothesis above. How can I know the correct
ordering of the core scores so that I achieve correct multiplication ?
Thanks,
Salameh
