Abstract

Finite tree transducers can be used to describe simple transformations on structured documents. The talk considers deterministic topdown tree transducers and shows that each of them is equivalent to a corresponding canonical transducer. This result generalizes a corresponding construction for deterministic word transducers by Mohri. It allows for a simpler method for deciding equivalence of topdown transducers and also opens up possiblities for learning transducers from examples.
