ACE-related Functionality

The ACE (Automatic Content Extraction) evaluations run by NIST from 2000 to 2009 define a quite general set of information extraction tasks, including entities, (binary) relations, and events. Jet provides full support for these tasks using a set of corpus-trained extraction components. This includes the ace command, which performs the full Ace extraction task, and a variety of support utilties for training and scoring individual components. These utilities are invoked by

xjet utilityName file-argument-1 file-argument-2 ...

The following utilities are invoked using this format:

Utility name	function
AceJet.APFtoXML	convert name information in APF file to in-line XML tags
AceJet.LearnAceRelations	train relation tagger
AceJet.RelationScorer	score ACE relations
AceJet.TrainEventTagger	train event tagger
AceJet.EventTagger	run event tagger in diagnostic mode (given perfect entities and values)
AceJet.EventScorer	score ACE events
