{"url":"/task/temporal-information-extraction","name":"Temporal Information Extraction","slug":"temporal-information-extraction","description_markdown":"Temporal information extraction is the identification of chunks/tokens corresponding to temporal intervals, and the extraction and determination of the temporal relations between those. The entities extracted may be temporal expressions (timexes), eventualities (events), or auxiliary signals that support the interpretation of an entity or relation. Relations may be temporal links (tlinks), describing the order of events and times, or subordinate links (slinks) describing modality and other subordinative activity, or aspectual links (alinks) around the various influences aspectuality has on event structure.\r\n\r\nThe markup scheme used for temporal information extraction is well-described in the ISO-TimeML standard, and also on [www.timeml.org](http://www.timeml.org).\r\n\r\n```\r\n\r\n\r\n\r\n\r\n\r\n\r\n PRI20001020.2000.0127 \r\n NEWS STORY \r\n 10/20/2000 20:02:07.85 \r\n\r\n\r\n The Navy has changed its account of the attack on the USS Cole in Yemen.\r\n Officials now say the ship was hit nearly two hours after it had docked.\r\n Initially the Navy said the explosion occurred while several boats were helping\r\n the ship to tie up. The change raises new questions about how the attackers\r\n were able to get past the Navy security.\r\n\r\n\r\n 10/20/2000 20:02:28.05 \r\n\r\n\r\n\r\n\r\n\r\n\r\n```\r\n\r\nTo avoid leaking knowledge about temporal structure, train, dev and test splits must be made at document level for temporal information extraction.","categories":[{"name":"Natural Language
