| Evaluation | The results for W-DITG are listed in Table l. Tests 1 and 2 show that with the same beam size (i.e. |
| Evaluation | To enable TTT achieving similar F-score or F-score upper bound, the beam size has to be doubled and the time cost is more than twice the original (c.f. |
| Evaluation | This also explains (in Tables 2 and 3) why DPDI with beam size 10 leads to higher Bleu than TTT with beam size 20, even though both pruning methods lead to roughly the same alignment F-score |
| Pruning in ITG Parsing | The third type of pruning is equivalent to minimizing the beam size of alignment hypotheses in each hypernode. |
| The DPDI Framework | Note that the beam size (max number of E-spans) for each F-span is 10. |
