This paper describes the UZH system that was used for the WMT 2011 system combination shared task submission.
We participated in the system combination task for the translation directions DE-EN and EN-DE.
The system uses Moses as a backbone, with the outputs of the 2-3 best individual systems being integrated through additional phrase tables.
The system compares well to other system combination submissions, with no other submission being significantly better.
A BLEU-based comparison to the individual systems, however, indicates that it achieves no significant gains over the best individual system.
