Unsupervised Parsing with S-DIORA: Single Tree Encoding for Deep Inside-Outside Recursive Autoencoders (2020.emnlp-main)
Copied to clipboard
| Challenge: | Syntactic parse trees are valuable intermediate features for many NLP pipelines. |
| Approach: | They propose an improved version of DIORA that encodes a single tree rather than a softly-weighted mixture of trees by employing a hard argmax operation and a beam at each cell in the chart. |
| Outcome: | The proposed model improves state-of-the-art in constituency parsing on the English WSJ Penn Treebank by 2.2-6% F1, depending on the data used for fine-tuning. |
