Table 1 gives the results of these experiments and compares them with some other statistical parsers ( resp . Collins 1996 , Charniak 1997 , Collins 1999 and Charniak 2000 ) . While the PCFG reduction of Bod ( 2001 ) obtains state-of-the-art results on the WSJ , comparable to Charniak ( 2000 ) , Bonnema et al. 's estimator performs worse and is comparable to Collins ( 1996 ) .
