| summary | Over the past years, major effort was spent on incorporating
monolingual syntax into statistical machine translation with
mixed results. One difficulty in doing so often seems that
translation equivalence does not necessarily conform to monolingual
syntactic constituency structure, as assumed by traditional
compositional semantics. In this talk I will reflect on syntactic
structure aiming to show that the information represented in
a syntactic tree can be represented in alternative ways.
By representing this information in terms of translation equivalence,
syntactic information can be brought into statistical MT models
effectively. In the talk I will give a bird's-eye view of three
recent models developed together with my co-workers and touch upon
some relevant aspects of the interplay between syntax and SMT.
Subsequently, I will give a brief overview of the problem of how to
represent the translation mapping hierarchically in order to capture the
relations of translation equivalence adequately. I will also briefly
discuss how to use this new hierarchical representation to pave
the way for learning compositional statistical synchronous grammars
from word-aligned parallel corpora. |
