Neural machine Translation
Statistical Machine Translation
Complex rules may be too specific to be generally useful and also increase the complexity of parsing. Hence, we may want tp binarize either the parse trees from which rules are extracted or the rules themselves.
Binarizing SCFG is the main subject of 10 publications. 5 are discussed here.
