Coordination Annotation for the Penn Treebank is a stand-off annotation for the Wall Street Journal portion of Treebank-3 (PTB3) (LDC99T42) developed by researchers at the University of Düsseldorf and Indiana University. It marks all tokens that have a coordinating function (potentially among other functions).
Coordination is a syntactic structure that links together two or more elements known as conjuncts or conjoins. The presence of coordination is often signaled by the appearance of a coordinator (coordinating conjunction), such as and, or, but in English.
Penn Coordination Annotation is available at no cost to all licensees of PTB3 and appears in their download queue associated with LDC99T42 as penn_coordination_anno_LDC2015T08.tgz.
