For example, adding the phrasal verb "ask someone out" as a constraint would mean using "ask" as constraint 0 and "out" as constraint 1 , with two filters: one requiring that constraint 1 cannot be used before constraint 0 , and another requiring that there must be at least one generated token between the constraints.
experiments show that GBS can provide large improvements in translation quality in interactive scenarios, and that, even without any user input, GBS can be used to achieve significant gains in performance in domain adaptation scenarios.
