automated extraction of tags from the penn treebank
John Chen K Vijay-Shanker
As these formalisms are fully lexicalized with an invariant ( LTAG and CCG ) or limited ( HPSG ) rule component , the extraction of a lexicon essentially amounts to the creation of a grammar . Chen and Vijay-Shanker ( 2000 ) explore a number of related approaches to the extraction of a lexicalized TAG from the Penn-II Treebank with the aim of constructing a statistical model for parsing . The extraction procedure utilizes a head percolation table as introduced by Magerman ( 1995 ) in combination with a variation of Collins 's ( 1997 ) approach to the differentiation between complement and adjunct .
