Tom, The original paper is Xiong et al (2011) "Enhancing Language Models in Statistical Machine Translation with Backward N-grams and Mutual Information Triggers" http://aclweb.org/anthology//P/P11/P11-1129.pdf
I implemented the backward n-gram functionality in Moses, beginning with the following commit: https://github.com/moses-smt/mosesdecoder/commit/8459a86137f7d15834009557a62c4278479da088 You can browse my subsequent related commits: https://github.com/moses-smt/mosesdecoder/commits?author=dowobeha Lane On Mon, Feb 3, 2014 at 2:13 PM, Tom Hoar <[email protected]> wrote: > I've seen several references to "backward LM" on the list.
