EXCEEDS: Extracting Complex Events via Nugget-based Grid Modeling in Scientific Domain

The article announces the release of SciEvents, a large-scale multi-event document-level dataset specifically designed for the scientific domain, consisting of 2,508 documents and 24,381 events, along with the EXCEEDS framework for event extraction. EXCEEDS employs a nugget-based grid modeling approach to encode dense nuggets, simplifying complex event extraction tasks. This release is significant for practitioners as it provides tailored resources and methodologies to enhance event extraction capabilities in scientific research, an area previously lacking comprehensive support.
