Evidence-Based Word Alignment

• In this paper we describe word alignment experiments using an approach based on a disjunctive combination of alignment evidence. A wide range of statistical, orthographic and positional clues can be combined in this way. Their weights can easily be learned from small amounts of hand-aligned training data. We can show that this “evidence-based” approach can be used to improve the baseline of statistical alignment and also outperforms a discriminative approach based on a maximum entropy classifier.
