Word Alignment in the Era of Deep Learning: A Tutorial
Essentially word alignment decomposes the task of translating an entire sentence into translating parts of it Och and Ney(2003) present the following formalization of word alignment Given a source string F= f 1;:::;f j;:::;f mand a target string E= e 1;:::;e i;:::;e n an alignment Ais a subset of the Cartesian product of word positions: |
What is word alignment?
Word alignment is typically done after sentence alignment has already identified pairs of sentences that are translations of one another. Bitext word alignment is an important supporting task for most methods of statistical machine translation.
Can unsupervised bitext mining and unsupervised Word alignment produce high quality lexicons?
In this paper, we show it is possible to produce much higher quality lexicons with methods that combine (1) unsupervised bitext mining and (2) unsupervised word alignment.
What is Bitext word alignment?
Bitext word alignment or simply word alignment is the natural language processing task of identifying translation relationships among the words (or more rarely multiword units) in a bitext, resulting in a bipartite graph between the two sides of the bitext, with an arc between two words if and only if they are translations of one another.
What is the best word alignment tool?
Other popular statistical word alignment tools are fast_align (Dyer, Chahuneau, and Smith 2013), and Berkeley Aligner (Liang, Taskar, and Klein 2006). These are discussed briefly in Appendix A.2. GIZA++ is an unsupervised word alignment tool, which works by leveraging language-independent statistical methods.
