    Incorporating semantic structure into a linguistics-free
    translation model is challenging, since semantic structures are
    closely tied to syntax. In this paper, we propose a two-level
    approach to exploiting predicate-argument structure reordering in
    a hierarchical phrase-based translation model. First, we
    introduce linguistically motivated constraints into a
    hierarchical model, guiding translation phrase choices in favor
    of those that respect syntactic boundaries. Second, based on such
    translation phrases, we propose a predicate-argument structure
    reordering model that predicts reordering not only between an
    argument and its predicate, but also between two
    arguments. Experiments on Chinese-to-English translation
    demonstrate that both advances significantly improve translation
    accuracy.
