Leveraging fine-tuned Large Language Models with LoRA for Effective Claim, Claimer, and Claim Object Detection (2024.eacl-long)
Copied to clipboard
| Challenge: | Existing work on identifying claims has focused on sentence level, neglecting supplementary attributes such as the claimer and claim object of the claim. |
| Approach: | They propose a novel approach to detect claims using large language models in natural language understanding and text generation. |
| Outcome: | The proposed approach transforms claim, claimer and claim object detection task into QA setting. |

| Challenge: | Large-scale Multi-label Text Classification (LMTC) is a type of classification that assigns labels to a large set of labels. |
| Approach: | They propose to use probabilistic label trees to improve frequent, few and zero-shot learning . they propose to combine a new state-of-the-art method with pre-trained Transformers . |
| Outcome: | The proposed models outperform existing models on frequent, few and zero-shot learning on three datasets from different domains. |
