Analysis of MultiWord Expression translation errors in Statistical Machine Translation

Abstract

In this paper, we analyse the usage of multiword expressions in Statistical Machine Translation. We exploit the Moses SMT toolkit to train models for French-English and Czech-Russian language pairs.

For each language pair, two models were built: a baseline model without additional MWE data and the model enhanced with information on MWE. For the French-English pair, we tried three methods of introducing the MWE data.

For Czech-Russian pair, we used just one method - adding automatically extracted data as a parallel corpus.
