the phrase translation and lexical probabilities for the phrase pairs <ē m ,f ′ m > derived using the method in Section 3.1.
we use the phrase translation probabilities p(f ′ m |ē m ) and p(ē m |f ′ m ), as well as the lexical translation probabilities p lex (f ′ m |ē m ) and p lex (ē m |f ′ m ) as calculated in (Koehn et al., 2003).
