2005;Ganchev, Gillenwater, and Taskar 2009); discovery of paraphrases (Bannard and Callison-Burch 2005); and joint unsupervised POS and parser induction across languages (Snyder and Barzilay 2008).
using this decoding we include an alignment link i − j if the posterior probability that word i aligns to word j is above some threshold.
