Abstract

Different works on training of log-linear interpolation models for statistical machine translation reported performance improvements by optimizing parameters with respect to translation quality, rather than to likelihood oriented criteria. This work presents an alternative mini- mum error-rate training procedure based on structural support vector machines (SSVMs) for log-linear interpolation models which is not lim- ited to the model scaling factors and needs only few iterations to con- verge. Experimental results are reported on the Spanish­English Eu- roparl corpus.
