the number of hyperedges would be exponential in
n. Instead, we include only the top k n-ary back-
traces for each forest ... 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
