Challenge: Recent work on document-level event argument extraction models each individual event in isolation and therefore causes inconsistency among extracted arguments across events.
Approach: They propose an event-aware argument extraction model with augmented context to improve consistency . they hypothesize that participants tend to play consistent roles across multiple events in a document .
Outcome: The proposed model improves consistency and accuracy of arguments extracted from documents.

Challenge: Recent studies on event argument extraction (EAE) have not taken event co-occurrences into account.

Outcome: The proposed framework can extract arguments of multiple events in parallel.
