Copied to clipboard
| Challenge: | Existing methods of generating counterfactual samples are not fully utilized in the task of Visual Question Answering (VQA). |

Post-Training Dialogue Summarization using Pseudo-Paraphrasing (2022.findings-naacl)
Copied to clipboard
| Challenge: | Existing approaches to dialogue summarization use dialogue-specific features that require additional knowledge to recognize or make the models harder to tune. |
| Approach: | They propose to post-train pretrained language models to rephrase from dialogue to narratives and fine-tune them as usual. |
| Outcome: | The proposed approach outperforms existing models by summary quality and implementation costs. |
Incomplete Utterance Rewriting by A Two-Phase Locate-and-Fill Regime (2023.findings-acl)
Copied to clipboard
| Challenge: | Existing models with incomplete utterances have too large search space, resulting in poor quality of rewriting results. |
| Approach: | They propose a 2-phase rewriting framework which predicts empty slots in the utterance that need to be completed and generates the part to be filled into each position. |
| Outcome: | The proposed framework achieves state-of-the-art results on several public rewriting datasets. |
A Diverse and Effective Retrieval-Based Debt Collection System with Expert Knowledge (2025.naacl-industry)
Copied to clipboard
| Challenge: | Existing debt collection systems lack script diversity, contextual relevance and coherence due to their complexity. |
| Approach: | They propose a script library based on real-world debt collection conversations and a retrieval based response system for contextual relevance. |
