... rule Markov model can condition on longer and sparser derivation his- tories. Among them, Ding and Palmer (2005) also use a dependency treelet model similar to Quirk and Menezes (2006), and Liu and ... tree -to- string grammars with rule Markov models. Huang and Mi (2010) have recently introduced an efficient incremental decoding algorithm for tree -to- string translation, w...
