MiniConGTS: A Near Ultimate Minimalist Contrastive Grid Tagging Scheme for Aspect Sentiment Triplet Extraction (2024.emnlp-main)
Copied to clipboard
| Challenge: | Existing approaches within the pretraining-finetuning paradigm tend to meticulously craft complex tagging schemes and classification heads, or incorporate external semantic enhancements to enhance performance. |
| Approach: | They propose to integrate a minimalist tagging scheme and a novel token-level contrastive learning strategy to improve pretrained representations. |
| Outcome: | The proposed framework achieves comparable or superior performance compared to state-of-the-art techniques while featuring a more compact design and reduced computational overhead. |
