QAEVENT: Event Extraction as Question-Answer Pairs Generation (2024.findings-eacl)
Copied to clipboard
| Challenge: | a novel approach to document-level event extraction requires linguistic expertise. |
| Approach: | They propose a question-and-answer-pair representation of document-level events as question and answer pairs (QAEVENT) this allows for more scalable and faster annotations from crowdworkers without linguistic expertise. |

DocEE: A Large-Scale and Fine-grained Benchmark for Document-level Event Extraction (2022.naacl-main)
Copied to clipboard
| Challenge: | Existing datasets focus on sentence-level event extraction, but document-level EE is limited due to the lack of large-scale and practical training and evaluation datasets. |
| Approach: | They propose a document-level event extraction dataset with 27,000+ events and 180,000+ arguments. |
| Outcome: | The proposed dataset includes 27,000+ events, 180,000+ arguments and large-scale manual annotations, fine-grained argument types and application-oriented settings. |

A Two-Stream AMR-enhanced Model for Document-level Event Argument Extraction (2022.naacl-main)
Copied to clipboard
| Challenge: | Existing studies aim at extracting event arguments from a single sentence . document-level event extraction still remains under-explored . |
| Approach: | They propose a two-stream abstract meaning representation enhanced extraction model to extract event arguments from an entire document. |
| Outcome: | The proposed model outperforms state-of-the-art in extracting event arguments from documents by 2.54 F1 and 5.13 F1 on public RAMS and WikiEvents datasets. |
Event-Keyed Summarization (2024.findings-emnlp)
Copied to clipboard
| Challenge: | a novel task combines document-level event extraction with event-keyed summarization . a recent study has shown that traditional summarizing produces inferior summaries of target events . |
| Approach: | They propose a task that marries traditional summarization and document-level event extraction with the goal of generating a contextualized summary for a specific event, given a document and an extracted event structure. |
| Outcome: | The proposed task combines document-level event extraction with event-keyed summarization . the authors show that the proposed task is robust and humane . |
An Iteratively Parallel Generation Method with the Pre-Filling Strategy for Document-level Event Extraction (2023.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods to generate event roles require a given generation order . parallel methods suffer from inadequate training and manifest zero accuracies on some event roles. |
| Approach: | They propose an iteratively parallel generation method with the Pre-Filling strategy to generate event roles in parallel to avoid order selection. |
| Outcome: | The proposed method outperforms other entity-enhanced models and achieves state-of-the-art performance on two public datasets. |
Document-Level Event Role Filler Extraction using Multi-Granularity Contextualized Encoding (2020.acl-main)
Copied to clipboard
| Challenge: | Document-level event extraction requires a view of a larger context to determine which spans of text correspond to event role fillers. |
| Approach: | They propose a multi-granularity reader to dynamically aggregate information captured by neural representations learned at different levels of granularities. |
| Outcome: | The proposed model performs substantially better than previous models on the MUC-4 event extraction dataset. |
Probing Representations for Document-level Event Extraction (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Document-level information extraction tasks require a more comprehensive understanding that often extends to the entire input document. |
| Approach: | They propose to use probing to analyze document-level information extraction representations by embedding probes into a standard dataset. |
| Outcome: | The proposed models improve argument detections but struggle with document length and cross-sentence discourse. |
