Abstract
Machine translation phrase table augmentation embodiments are described that employ an automatic syntax-based scheme to produce additional phrase pairs and insert them into a phrase table. One general process implementing this augmentation involves inputting one or more syntactic transfer patterns, and for each pattern synthesizing phrases in a source language of the type associated with the pattern using a source language lexicon. Phrases, such as those not found in a monolingual corpus of the source language, are eliminated from the synthesized phrases. Each of the remaining synthesized phrases is then translated into the target language using the syntactic transfer pattern, a bilingual source-to-target language dictionary, and a morphological synthesizer. Those translated phrases not found in a monolingual corpus of the target language are then eliminated. Phrase pairs made up of a remaining translated phrase and its corresponding source language phrase are then added to the phrase table being augmented.
