... one on the combined English halves of the bitexts, and one on two billion words of English. These were smoothed using modified Kneser-Ney (Chen and Goodman, 1998) and stored using randomized data structures ... both the source and target language. We dis- cuss the reasons why this has been a chal- lenge, review existing attempts to meet this challenge, and show how some old and n...

One approach is to use uniform random sampling ... and WMEB using just the hand-picked seeds (S hand ) and 50 sample super- vised bagging (S gold BAG). Bagging with samples from S gold successfully increased the performance of...
