... are determined by their relative positions in the target language – the node in the most front gets the high- est rank, while the ending word in the target sentence gets the lowest rank. The ranking ... significantly reduces the crossing-link numbers over the original sentence pairs. On the other hand, the performance of the ranking reorder model still fall far short...

... head, we greedily take the root word of the sentence as their heads. In order to fully use the training data, if there are directed cycles in the result dependency graph, we still use the graph in our ... t0→c16). Since the PASs use the non-terminal nodes in the HPSG tree (Figure 1), this prevents their direct us- age in a string-to-dependency decoder. We thus need an algorith...
