This paper describes the JHU system combination scheme used in WMT-11. The JHU system combination is based on confusion network alignment, and inherited the framework developed by (Karakos et al., 2008). We improved our core system combination algorithm by making use of TER-plus, which was originally designed for string alignment, for alignment of confusion networks. Experimental results on French-English, German-English, Czech-English and Spanish-English combination tasks show significant improvements on BLEU and TER by up to 2 points on average, compared to the best individual system output, and improvements compared with the results produced by ITG which we used in WMT-10.
