Papers with Boundary Shift Loss
Negation Scope Refinement via Boundary Shift Loss (2023.findings-acl)
Copied to clipboard
| Challenge: | Negation detection is a complex linguistic phenomenon with long spans . existing methods tend to make wrong predictions around the scope boundaries . |
| Approach: | They propose a model which engages the Boundary Shift Loss to refine the predicted boundary. |
| Outcome: | The proposed model refines the predicted boundary on multiple datasets. |
