A Learning-Exploring Method to Generate Diverse Paraphrases with Multi-Objective Deep Reinforcement Learning (2020.coling-main)
Copied to clipboard
| Challenge: | Paraphrase generation is of great importance for many downstream tasks in natural language processing. |
| Approach: | They propose a method to generate sentences as learning objectives from the learned data distribution and employ reinforcement learning to combine these new learning objectives for model training. |
| Outcome: | The proposed method gains significant diversity and improves generation quality over state-of-the-art datasets. |
Syntactically-Informed Unsupervised Paraphrasing with Non-Parallel Data (2021.emnlp-main)
Copied to clipboard
| Challenge: | Existing studies on syntactically controlled paraphrase generation rely on large-scale parallel data. |
| Approach: | They propose a syntactically-informed unsupervised paraphrasing model based on conditional variational auto-encoder which can generate texts in a specified syntastic structure. |
| Outcome: | The proposed model can generate diverse paraphrases with specified syntactic structure using non-parallel data. |
Long Text Generation with Topic-aware Discrete Latent Variable Model (2022.emnlp-main)
Copied to clipboard
| Challenge: | Recent work focuses on the modeling of discourse relation, resulting in discrete codes learning shallow semantics. |
| Approach: | They propose a topic-aware latent code-guided text generation model that encourages discrete codes to model information about topics. |
| Outcome: | The proposed model generates more topic-relevant and coherent texts. |
Learning Structural Information for Syntax-Controlled Paraphrase Generation (2022.findings-naacl)
Copied to clipboard
| Challenge: | Syntax-controlled paraphrase generation aims to produce paraphrase conform to given syntactic patterns. |
| Approach: | They propose a model that captures parent-child and sibling relations and a syntax encoder to capture alignment relations. |
| Outcome: | The proposed model achieves state-of-the-art in terms of semantic and syntactic quality on two popular benchmark datasets. |
