He draws the conclusion that a small amount of matched training data is better than a large amount of unmatched training data. ... WSJ, high accuracy parsing models have been created, some of them using extensions to classical PCFG parsing such as lexicalization and markovization (Collins, 1999; Charniak, 2000; Klei...
