... language independent method for alignment of parallel texts that makes use of homograph tokens for each pair of languages. In order to filter out tokens that may cause misalignment, we use confidence ... of candidate correspondence points for parallel texts alignment without recurring to heuristics as in previous work. The alignment is not restricted to sentence or paragraph level...

ITGs per- form string-to-string alignment, but do so through a parsing algorithm that will allow us to inform the objective ... cohesion constraint: for every possible alignment, a corre- sponding binary constituency tree must exist for which the alignment maintains phrasal cohesion.
