First, we perform an intrinsic evaluation of the effectiveness of our domain-tuning techniques by comparing our domain-tuned lexicon to a manually constructed domain-specific bilingual termlist. Our results indicate that we achieve 66\% recall and 95\% precision with respect to a human-derived gold standard. Next, an extrinsic evaluation demonstrates that our domain-tuned lexicon improves the Bleu scores 50\% over a statistical system{\textemdash}with a smaller improvement when the system is trained on a uniformly-weighted dictionary. }, author = {Ayan,N.F. and Dorr, Bonnie J and Kolak,O.} }
