... of tar- get language sentences is impracticable (τ is an infinite set), the translation sentence is usually built incremen- tally, composing partial translations of the source sen- tence, which ... words. In contrast, the translation con- text is differently taken into account. Whereas phrase- based decoders employ translation units uncontextual- ized, MARIE takes the translation unit contex...
