ATGL: An Adaptive-Threshold Global Loss for Document-level Relation Extraction (2026.acl-long)
Copied to clipboard
| Challenge: | Document-level relation extraction (DocRE) aims to determine which relations hold between a given entity pair in a document. |
| Approach: | They propose a document-level relation extraction paradigm that decouples existing losses into independent positive and negative losses, which interact solely with a shared threshold. |
| Outcome: | The proposed model outperforms existing models on four datasets and achieves state-of-the-art results. |
An Adaptive Multi-Threshold Loss and a General Framework for Collaborating Losses in Document-Level Relation Extraction (2025.findings-acl)
Copied to clipboard
| Challenge: | Document-level relation extraction (DocRE) aims to identify relations for a given entity pair within a document. |
| Approach: | They propose to partition the label space into different sub-label spaces and learn an adaptive threshold for each sub-labeled space. |
| Outcome: | The proposed model outperforms single-loss methods on the concurrent application of multiple losses across four datasets. |
DEBAR: Mitigating Contextual Bias in Cross-Document Relation Extraction via Dual-Stream Decoupling (2026.acl-long)
Copied to clipboard
| Challenge: | Existing methods focus on sentence-level or singledocument settings, resulting in one-sided relation transfer contextual bias and incomplete reasoning chains. |
| Approach: | They propose a framework to explicitly decouple and preserve bidirectional bridge evidence and a dynamic loss optimization objective to separate head and tail contexts. |
| Outcome: | The proposed framework decouples and preserves bidirectional bridge evidence while capturing global dependencies through iterative message passing. |
Entity Pair-guided Relation Summarization and Retrieval in LLMs for Document-level Relation Extraction (2025.findings-naacl)
Copied to clipboard
| Challenge: | Document-level relation extraction (DocRE) aims to extract relations between entities in a document. |
| Approach: | They propose an entity pair-guided relation summarization and retrieval model for DocRE . the model uses entity pairs to guide relation summaries and retrievals . |
| Outcome: | The proposed model achieves state-of-the-art (SOTA) performance on three datasets. |
Rethinking the Role of LLMs for Document-level Relation Extraction: a Refiner with Task Distribution and Probability Fusion (2025.naacl-long)
Copied to clipboard
| Challenge: | Document-level relation extraction (DocRE) provides a broad context for extracting relations for entities. |
| Approach: | They propose a method that utilizes LLMs as a refiner and task distribution and probability fusion to refine LLM-based relation extraction methods. |
| Outcome: | The proposed method outperforms existing LLM-based methods without fine-tuning by 25.2% F1. |
ET-MIER: Entity Type-guided Key Mention Identification and Evidence Retrieval for Document-level Relation Extraction (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Existing work does not fully distinguish the contribution of different mentions to entity representation and the importance of mentions in evidence sentences. |
| Approach: | They propose a document-level relation extraction task that uses entity mentions to identify relations between entities in a text. |
| Outcome: | The proposed model achieves state-of-the-art on widely-adopted datasets. |
