Papers with sentence-level paraphrase generation
Towards Document-Level Paraphrase Generation with Sentence Rewriting and Reordering (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Document-level paraphrase generation is an important task in natural language processing. |
| Approach: | They propose a coherence relationship-guided paraphrase generation model that leverages graph GRU to encode the coherency relationship graph and get the cohesion-aware representation for each sentence. |
| Outcome: | The proposed model outperforms baseline models on BERTScore and diversity scores. |
How to Ask Good Questions? Try to Leverage Paraphrases (2020.acl-main)
Copied to clipboard
| Challenge: | Existing methods to generate human-like questions rely on paraphrases to generate good questions. |
| Approach: | They propose to integrate paraphrase knowledge into question generation to generate human-like questions by combining paraphrases with a back-translation method. |
| Outcome: | The proposed model achieves obvious performance gain over several strong baselines and human evaluation validates that it can ask questions of high quality by leveraging paraphrase knowledge. |
