Abstract

This is an extended version of a paper with the same title published in ASRU, 2005. We present a new multilingual statistical MT word alignment model based on a simple extension of the IBM and HMM Models and a two-step alignment procedure. Preliminary results on a small hand-aligned subset of the Europarl corpus show a 7\% relative improvement over a state of the art alignment model.
