Abstract

This paper describes the joint QUAERO submission to the WMT 2011 machine translation evaluation. Four groups (RWTH Aachen University, Karlsruhe Institute of Technology, LIMSI-CNRS, and SYSTRAN) of the QUAERO project submitted a joint translation for the WMT German→English task. Each group translated the data sets with their own systems. Then RWTH system combination combines these translations to a better one. In this paper, we describe the single systems of each group. Before we present the results of the system combination, we give a short description of the RWTH Aachen system combination approach.
