Revisiting Syntax-Based Approach in Negation Scope Resolution (2023.starsem-1)
Copied to clipboard
| Challenge: | Existing methods for negation scope resolution without syntactic structure performed better. |
| Approach: | They re-evaluate the effectiveness of syntactic structure in negation scope resolution . they replace the parser employed in previous studies with state-of-the-art parsers . |
| Outcome: | The proposed method performs better without syntactic structure than previous methods . the proposed method is comparable to state-of-the-art methods based on heuristic rules . |
Negation Scope Conversion: Towards a Unified Negation-Annotated Dataset (2024.lrec-main)
Copied to clipboard
| Challenge: | Negation scope resolution models that use pre-trained language models perform worse when fine-tuned on a combined dataset. |
| Approach: | They propose to automatically convert the negation scopes of BioScope and SFU to those of Sherlock and merge them into a unified dataset. |
| Outcome: | The proposed method improves on the unified dataset compared to the simply combined dataset. |
