Efficient Inference through Cascades of Weighted Tree Transducers
Weighted tree transducers have been proposed as useful formal models for representing syntactic natural language processing applications, but there has been little description of ...

On Typechecking Top-Down XML Tranformations: Fixed Input or Output Schemas
Typechecking consists of statically verifying whether the output of an XML transformation always conforms to an output type for documents satisfying a given input type. In this ge...

Linear Context-Free Rewriting Systems and Deterministic Tree-Walking Transducers
We show that the class of string languages generated by linear context-free rewriting systems is equal to the class of output languages of deterministic treewalking transducers. F...

Exact XML Type Checking in Polynomial Time
Stay macro tree transducers (smtts) are an expressive formalism for reasoning about XSLT-like document transformations. Here, we consider the exact type checking problem for smtts....

Higher-Order Multi-Parameter Tree Transducers and Recursion Schemes for Program Verification
We introduce higher-order, multi-parameter, tree transducers (HMTTs, for short), which are kinds of higher-order tree transducers that take input trees and output a (possibly infi...
