... top- down and left-corner parsing (Roark, 2001a; Roark, 2001b) and head-driven parsing (Charniak, 2001) approaches have directly used generative PCFG models as language models. In the work of Wen Wang ... Previous Work Techniques for exploiting stochastic context-free grammars for language modeling have been ex- plored for more than a decade. Early approaches included algorit...
