DFKI's SC and MT Submissions to IWSLT 2011
4 Proceedings of International Workshop on Spoken Language Translation, San Francisco, CA, USA, o.A., 12/2011
 
We describe DFKI’s submission to the System Combination and Machine Translation tracks of the 2011 IWSLT Evalua- tion Campaign. We focus on a sentence selection mechanism which chooses the (hopefully) best sentence among a set of candidates. The rationale behind it is to take advantage of the strengths of each system, especially given an heterogeneous dataset like the one in this evaluation campaign, composed of TED Talks of very different topics. We focus on using features that correlate well with human judgement and, while our primary system still focus on optimizing the BLEU score on the development set, our goal is to move towards optimiz- ing directly the correlation with human judgement. This kind of system is still under development and was used as a sec- ondary submission.
