We describe a grammarless method for simultaneously bracketing both halves of a parallel text and giving word alignments, assuming only a translation lexicon for the language pair. We introduce inversion-invariant transduction grammars which serve as generative models for parallel bilingual sentences with weak order constraints. Focusing on Wansduction grammars for bracketing, we formulate a normal form, and a stochastic version amenable to a maximum-likelihoodbracketing algorithm. Several extensions and experiments are discussed. ...
