Noun phrase translation

We define noun phrase translation as a subtask of statistical machine translation. This enables us to build a dedicated noun phrase translation subsystem that improves over the currently best general statistical machine translation methods by incorporating special modeling and special features. We integrate such a system into a state-of-the-art statistical machine translation system with novel methods and show overall improvement in translation quality. We also carry out empirical linguistic studies on noun phrase translatability and the sources of translation errors.
