Various parsing techniques have been developed for lexicalized grammars such as Lexicalized Tree Adjoining Grammar (LTAG) (Schabes et al., 1988), and Head-Driven Phrase Structure Grammar (HPSG) (Pollard and Sag, 1994). Along with the independent development of parsing techniques for individual grammar formalisms, some of them have been adapted to other formalisms (Schabes et al., 1988; van Noord, 1994; Yoshida et al., 1999; Torisawa et al., 2000). However, these realizations sometimes exhibit quite different performance in each grammar formalism (Yoshida et al., 1999; Yoshinaga et al., 2001). .
