Now we briefly describe how to estimate the adapted lexical weight for phrase pairs, which can be adjusted in a similar way to the phrase probability.
adopting our method, each word is considered as one phrase consisting of only one word, so Here we obtain w(e|f, t f out ) with a similar approach to φ(ẽ|f , t f out ), and calculate P (t f out |t f in ) and P (t f in |f ) by resorting to formulas (8) and (9).
