Hi,

The phrase-table file has a score vector of 5 numbers. Two of them are
lexical weights.

If I understand it correctly, the lexical weights of a phrase pair are
computed by use of the word alignments within the phrase pair. But in a
large corpus of sentences we might encounter the same phrase with a
different word alignment, thus changing the value of the lexical weight.

How are these combined into the final translation table? Is this simply a
matter of averaging them or is there some more sophisticated method used?



Regards,

Sanne
