A detailed analysis of phrase-based and syntax-based machine
translation: the search for systematic differences.
In: AMTA, 28 Oct - 1 Nov 2012, San Diego, CA.
This paper describes a range of automatic and manual comparisons of phrase-based and syntax-based statistical machine translation methods applied to English-German and
English-French translation of user-generated content. The syntax-based methods underperform the phrase-based models and the relaxation of syntactic constraints to broaden translation rule coverage means that these models do not necessarily generate output which is more grammatical than the output produced by the phrase-based models. Although the
systems generate different output and can potentially
be fruitfully combined, the lack of systematic difference between these models makes the combination task more challenging.
