Paraphrase Identification. Events that are harder to detect could be found by noting that certain types of events occur together with higher probability, so once you find the easy events, it can help you find the harder ones. Previous work on extracting structured representations of events has focused largely on newswire text; Twitter's unique characteristics present new challenges and opportunities for open-domain event extraction. Document-level event extraction (DEE) is indispensable when events are described throughout a document.
