EAGER is a reinforcement learning framework that improves generative event extraction through fine-grained verifiable rewards and schema-contrastive advantage estimation, outperforming prompting, fine-tuning, and prior RL methods on seven benchmark datasets.
LA-RL introduces a label-aware self-reflection framework for reinforcement learning in information extraction, achieving consistent improvements on named entity recognition, relation extraction, and event extraction tasks with gains of up to 20 F1 on out-of-distribution benchmarks.
This paper presents a two-stage LLM-based system that extracts grounded event tags from SEC 8-K filings using a three-tier taxonomy of 119 event types, with mechanisms for constraint and auditability. The system is evaluated on nearly 300k filings, showing high precision for high-quality tags and enabling event studies that distinguish economically distinct events.
