Papers with Penn Treebank test set
Hexatagging: Projective Dependency Parsing as Tagging (2023.acl-short)
Copied to clipboard
| Challenge: | Using a pretrained language model, we can train language models on increasingly large amounts of data. |
| Approach: | They propose a dependency parser that constructs dependency trees by tagging words with elements from a finite set of possible tags. |
| Outcome: | The proposed approach achieves state-of-the-art performance of 96.4 LAS and 97.4 UAS on the Penn Treebank test set. |
Unsupervised Parsing via Constituency Tests (2020.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for unsupervised parsing rely on constituency tests . linguists can judge a sentence's grammatical validity by modifying it via some transformation . |
| Approach: | They propose a method for unsupervised parsing based on a constituency test . they specify a set of transformations and use an unsupervised neural acceptability model to make grammaticality decisions. |
| Outcome: | The proposed method achieves 62.8 F1 on the Penn Treebank test set, an improvement of 7.6 points over the previous best results. |
