Báo cáo khoa học: "Statistical parsing with an automatically-extracted tree adjoining grammar"

We discuss the advantages of lexicalized tree-adjoining grammar as an alternative to lexicalized PCFG for statistical parsing, describing the induction of a probabilistic LTAG model from the Penn Treebank and evaluating its parsing performance. We nd that this induction method is an improvement over the EM-based method of Hwa, 1998 , and that the induced model yields results comparable to lexicalized PCFG.
