Alignment of Parallel Corpora Exploiting Asymmetrically Aligned Phrases
Patrik Lambert, Núria Castell, Jordi Girona Salgado · 2006
This paper presents a simple way of producing symmetric, phrase-based alignments, combining two single-word based alignments. Our algorithm exploits the asymmetries in the superposition of the two word alignments to detect the phrases that must be aligned as a whole. It was run with baseline word alignments produced by the Giza++ software and improved these alignments. The ability to treat some groups of words as a whole is essential in applications like machine translation. The paper also addresses the difficulty of the alignment evaluation task. 1.
