Generalized chart constraints for efficient PCFG and TAG parsing (P18-2)
Copied to clipboard
| Challenge: | Existing pruning techniques limit chart constraints to PCFGs and cannot be applied to more expressive grammars. |
| Approach: | They propose to apply chart constraints to more expressive grammars and a neural tagger which predicts chart constraints at very high precision. |
| Outcome: | The proposed technique accelerates both PCFG and TAG parsing by two orders of magnitude while improving accuracy. |
