Revisiting subword tokenization: A case study on affixal negation in large language models (2024.naacl-long)
Copied to clipboard
| Challenge: | Negation is central to language understanding but is not properly captured by modern NLP methods. |
| Approach: | They propose to use subword tokenization methods to detect negation in large language models . they find that models can reliably recognize negation, despite mismatches in tokenization accuracy . |
| Outcome: | The proposed models can detect negation in English using subword tokenization methods despite some mismatches in tokenization accuracy and negation detection performance. |
Improving negation detection with negation-focused pre-training (2022.naacl-main)
Copied to clipboard
| Challenge: | Negation is a common linguistic feature that is crucial in many language understanding tasks. |
| Approach: | They propose a new approach to detect negation in language models using data augmentation and negation masking. |
| Outcome: | The proposed approach improves negation detection performance and generalizability over the strong baseline NegBERT. |
