The most recent work, DCFEE , attempted to explore DEE on ChFinAnn, by employing distant supervision (DS) (Mintz et al., 2009) to generate EE data and performing a two-stage extraction: 1) a sequence tagging model for SEE, and 2) a key-event-sentence detection model to detect the key-event sentence, coupled with a heuristic strategy that padded missing arguments from surrounding sentences, for DEE.
the sequence tagging model for SEE cannot handle multi-event sentences elegantly, and even worse, the context-agnostic argumentscompletion strategy fails to address the argumentsscattering challenge effectively.
