Title: Statistical Transfer MT Systems for French and German

Abstract: The AVENUE research group's statistical transfer system is a general framework for creating hybrid machine translation systems. It uses two main resources: a weighted synchronous context-free grammar, and a probabilistic bilingual lexicon of syntax-based word- and phrase-level translations. Over the last six months, we have developed new methods for extracting these resources automatically from parsed and word-aligned parallel corpora. In this talk, I will describe the resource-extraction process as it was applied to new French--English and German--English systems for the upcoming ACL workshop on statistical machine translation. Preliminary evaluation results --- both automatic and human-assessed --- will also be reviewed.
