Summary
Unlike word-to-phrase alignments, computing the alignment expectations for phrase-to-phrase alignments is generally intractable due to the exponential growth of possible combination of phrases and alignments. Because of this, previous attempts for building a joint phrase alignment model have been unsuccessful.
This paper describes the first tractable Phrase-to-Phrase Alignment Model using Gibbs Sampling.
Tests show translation improvements over Machine Translation Systems build using conventional methods.
