Hi All,

In http://www.statmt.org/moses/?n=FactoredTraining.ScorePhrases <http://www.statmt.org/moses/?n=FactoredTraining.ScorePhrases>, it was mentioned that there is a key-value pair field at the end of each entry of the phrase table. Now I have a phrase table that looks like the following:

, [X] ||| to the outside world [PP] ||| 0.00202802 0.0962381 1.14287e-06 7.14872e-10 0.00284822 0.367879 ||| 0-0 ||| 6 10647 1 ||| ||| {{Tree [PP [TO to] [NP [DT the] [JJ outside] [NN world]]]}}

where the last field looks like the key-value pair field as described.

My question is the following:

1. how can I get access to the contents in this field? e.g. suppose tp is a TargetPhrase instance, is tp->GetProperty(?Tree?) the right way to do it?
2. is the content of this field always loaded when initializing the decoder?

Thanks!

Regards,
