Temporal Relation Extraction in Clinical Texts: A Span-based Graph Transformer Approach (2025.acl-long)
Copied to clipboard
| Challenge: | Temporal information extraction from unstructured text is challenging due to complex clinical language, long documents, and sparse annotations. |
| Approach: | They propose a method for extracting clinical events and their temporal relations from unstructured text using the I2B2 2012 Temporal Relations Challenge corpus. |
| Outcome: | The proposed method improves state-of-the-art temporal information extraction with 5.5% improvement in tempeval F1 score over previous best and 8.9% improvement on long-range relations. |
