discriminative reranking for natural language parsing
M Collins
This is roughly an 11 % relative reduction in error rate over Charniak ( 2000 ) and Bods PCFG-reduction reported in Table 1 . Compared to the reranking technique in Collins ( 2000 ) , who obtained an LP of 89.9 % and an LR of 89.6 % , our results show a 9 % relative error rate reduction . While SL-DOP and LS-DOP have been compared before in Bod ( 2002 ) , especially in the context of musical parsing , this paper presents the The DOP approach is based on two distinctive features : ( 1 ) the use of corpus fragments rather than grammar rules , and ( 2 ) the use of arbitrarily large fragments rather than restricted ones .
