But while Bod 's estimator obtains state-of-the-art results on the WSJ , comparable to Charniak ( 2000 ) and Collins ( 2000 ) , Bonnema et al. 's estimator performs worse and is comparable to Collins ( 1996 ) .

We show that these PCFG-reductions result in a 60 times speedup in processing time w.r.t. Bod ( 2001 , 2003 ) . But while Bod 's estimator obtains state-of-the-art results on the WSJ , comparable to Charniak ( 2000 ) and Collins ( 2000 ) , Bonnema et al. 's estimator performs worse and is comparable to Collins ( 1996 ) . In the second part of this paper , we extend our experiments with a new notion of the best parse tree .
