Brown Laboratory for Linguistic Information Processing (BLLIP)1987-89 WSJ Corpus Release 1 contains a complete, Treebank-style part-of-speech (POS) tagged and parsed version of the three-year Wall Street Journal (WSJ) collection from ACL/DCI (LDC93T1), approximately 30 million words. The annotation was performed using statistically-based methods developed by BLIIP researchers Eugene Charniak, Don Blaheta, Niyu Ge, Keith Hall, John Hale and Mark Johnson.
This corpus both overlaps and supplements the million-word Penn Treebank (PTB) collection of parsed and POS-tagged WSJ texts.
The PTB project selected 2,499 stories from a three-year WSJ collection of 98,732 stories for syntactic annotation. These 2,499 stories are distributed in Treebank-2 (LDC95T7) and Treebank-3 (LDC99T42), both of which include the raw text for each story.
