... Collapsing Binarization To facilitate a change in binarization, we transform the translation forest into n-ary form. In the n-ary forest, each hyperedge corresponds to an original grammar rule, and ... Transforming the entire for- est to n-ary form is intractable, however, because the number of hyperedges would be exponential in n. Instead, we include only the top k n-ary back- traces fo...
