Abstract
Most current event extraction systems rely on local information at the phrase or sentence level.
Conclusion and Future Work
Experiments show that document-level information can improve the performance of a sentence-level baseline event extraction system .
Cross-event Approach
Our event extraction system is a two-pass system where the sentence-level system is first applied to make decisions based on local information.
Introduction
Most current event extraction systems are based on phrase or sentence level extraction.
Introduction
Several recent studies use high-level information to aid local event extraction systems .
Introduction
We extend these approaches by introducing cross-event information to enhance the performance of multi-event-type extraction systems .
Related Work
Almost all the current ACE event extraction systems focus on processing one sentence at a time (Grishman et al., 2005; Ahn, 2006; Hardy et al.
Related Work
They used this technique to augment an information extraction system with long-distance dependency models, enforcing label consistency and extraction template consistency constraints.

Experimental Setup
We randomly selected 12 document-image pairs from the test set and generated captions for them using the best extractive system , and two abstractive systems (word-based and phrase-based).
Results
Table 3 reports mean ratings for the output of the extractive system (based on the KL divergence), the two abstractive systems, and the human-authored gold standard caption.
Results
It is significantly worse than the phrase-based abstractive system (0c < 0.01), the extractive system (0c < 0.01), and the gold standard (0c < 0.01).
Results
Unsurprisingly, the phrase-based system is significantly less grammatical than the gold standard and the extractive system , whereas the latter is perceived as equally grammatical as the gold standard (the difference in the means is not significant).
