Hence, we also include a dependence on the word positions in the lexicon model p(e | f , i, j): Here, [(i , j) ∈ A] is 1 if (i , j) ∈ A and 0 otherwise.
the word e i depends not only on the aligned French word f j , but also on the number of preceding French words aligned with e i and on the number of the preceding English words aligned with f j .
