Tectogrammatical Annotation of the Wall Street Journal

This paper gives an overview of the current state of the Prague English Dependency Treebank project. It is an updated version of a draft text that was released along with a CD presenting the first 25% of the PDT-like version of the Penn Treebank – WSJ section (PEDT 1.0). Before the January 2009 release, the conversion from the original phrase structure trees into dependency trees as well as the consistency checks were substantially enhanced to savemanual work. The conversion is partly performed by scripted rules and partly by a statistical parser. To make the rules more powerful, the phrase-based Penn Treebank – WSJ was enriched with other publicly available language resources – the manual annotation of flat noun phrases and the named-entity and coreference tagging. At themoment, 50% of the 1million corpus have beenmanually annotated and consistencychecked on the tectogrammatical layer.
