Document-level Event Extraction with Efficient End-to-end Learning of Cross-event Dependencies

Abstract: Fully understanding narratives often requires identifying events in the context of whole documents and modeling the event relations. However, document-level event extraction is a challenging task as it requires the extraction of event and entity coreference, and capturing arguments that span across different sentences. Existing works on event extraction usually confine on extracting events from single sentences, which fail to capture the relationships between the event mentions at the scale of a document, as w… Show more

“…The model can deal with extended contexts that go beyond single phrases and does not require entity recognition or coreference resolution as a preprocessing step. Using DVN to capture cross-event dependencies while addressing event mention extraction, event co-reference, and entity co-reference, Huang et al [9] presented an end-to-end document-level event extraction model called DEED. DEED has a considerable advantage in the effectiveness of capturing inter-event correlations when using gradient ascent to build structured trigger predictions.…”

“…In some studies [13,14], the documentlevel event argument extraction task is considered as a populated paradigm that follows the MUC-4 task setting and is dedicated to extracting event arguments scattered in documents. In addition, Yang et al [8], Huang et al [15] and Li et al [7] follow the approach of first detecting the event type and then performing event arguments extraction. Specific event trigger words are first identified to determine the event type, and then event arguments beyond the sentence boundaries are extracted.…”
