Title:
What's in a translation rule?

Abstract:
In this talk, I will propose a theory that gives formal
semantics to word-level alignments defined over parallel corpora.
Moreover, I will discuss how this theory can be used to motivate a
linear-time algorithm that derives from word-aligned, parallel corpora a
minimal set of syntactically motivated transformation rules that explain
translation data.  This is joint work with Michel Galley (Columbia), Kevin
Knight (USC/ISI), and Daniel Marcu (USC/ISI).
