This adds a new string-to-tree decoder, which can be enabled with the -s2t option. It's intended to be faster and simpler than the generic chart decoder, and is designed to support lattice input (still WIP). For a en-de system trained on WMT14 data, it's approximately 40% faster in practice. For background information, see the decoding section of the EMNLP tutorial on syntax-based MT: http://www.emnlp2014.org/tutorials/5_notes.pdf Some features are not implemented yet, including support for internal tree structure and soft source-syntactic constraints.
