Hi, there are a number of different scores in the phrase table. The phrasal scores are normalized (they add up to one for each phrase that is conditioned on) - unless smoothing methods such as GoodTuring and KneserNey are used (then they add up to less than one).
The lexicalized scores are not normalized. For interpolation it generally not a good idea to normalize scores. -phi On Mon, Jan 21, 2013 at 12:35 AM, Barry Haddow <[email protected]> wrote: > Hi > > The phrase probabilities in Moses are normalised.
