The Generating Power of Total Deterministic Tree Transducers

Sebastian Maneth
1998 Information and Computation  
One abstraction which occurs when modeling attribute grammars by attributed tree transducers is that arbitrary trees over a ranked alphabet are taken as input, instead of derivation trees of a context-free  ...  Attributed tree transducers are abstract models to study properties of attribute grammars.  ...  I am grateful to Joost Engelfriet for the tremendous amount of helpful comments and suggestions for improvements on an earlier version of this paper.  ...

A Comparison of Tree Transductions Defined by Monadic Second Order Logic and by Attribute Grammars

Roderick Bloem, Joost Engelfriet
2000 Journal of computer and system sciences (Print)  
The attributed tree transducer is an attribute grammar in which all attributes are trees; it is preceded by a look-ahead phase in which all attributes have finitely many values.  ...  Two well-known formalisms for the specification and computation of tree transductions are compared: the mso graph transducer and the attributed tree transducer with look-ahead, respectively.  ...  On the other hand, attributed tree transducers have copy rules by which they can transport attribute values through the tree.  ...

Tree transducers with external functions

Zoltán Fülöp, Frank Herrmann, Sándor Vágvölgyi, Heiko Vogler
1993 Theoretical Computer Science  
However, not every macro tree transducer can be transformed into a one-visit attributed tree transducer, not even into an arbitrary noncircular attributed tree transducer.  ...  The first example illustrates the main idea of transforming a simple macro tree transducer into a one-visit attributed tree transducer.  ...  These are tree transducers in which the ranked alphabets of output symbols can contain special symbols, called external function symbols, which are interpreted by tree functions taken from an arbitrary  ...

Composing Stack-Attributed Tree Transducers

Keisuke Nakano
2008 Theory of Computing Systems  
This paper presents a composition method for stack-attributed tree transducers. Stackattributed tree transducers extend attributed tree transducers with a pushdown stack device for attribute values.  ...  Stack-attributed tree transducers are more powerful than attributed tree transducers due to the stack mechanism.  ...  Stack-Attributed Tree Transducers In this section, we give the definition of attributed tree transducers(ATT) and stack-attributed tree transducers(SATT).  ...

Approximate Data Exchange [chapter]

Michel de Rougemont, Adrien Vieilleribière
2006 Lecture Notes in Computer Science  
We consider a model based on transducers of words and trees, and study ε-Consistency, i.e., the problem of deciding whether a given source instance I is -close to a source I , whose image by a transducer  ...  We also show that ε-Typechecking on words can be solved in polynomial time, whereas the exact problem is PSPACE-complete.  ...  We showed that for the Edit distance with Moves, ε-Source-consistency is testable on words and trees, and that ε-Typechecking is polynomial on words.  ...

Context-Free Grammars with Storage [article]

Joost Engelfriet
2014 arXiv   pre-print
Taking particular storage types gives particular formalisms, such as indexed grammars, top-down tree transducers, attribute grammars, etc.  ...  The context-free S languages can be obtained from the deterministic one-way S automaton languages by way of the delta operations on languages, introduced in this paper.  ...  indexed tree transducers), in the same way as attribute gram- mars are equivalent to DRT(Tree-walk) transducers  ...

1983 Mathematical Reviews  
We show that the domain of attributed tree transformations is a regular tree language, and an alternative proof is given for the decidability of the K-visit property of deterministic attributed tree-transducers  ...  The proof is based on a decomposition result for linear (tree-) homomorphisms which is of interest on its own.  ... 

Approximate schemas, source-consistency and query answering

Michel de Rougemont, Adrien Vieilleribière
2008 Journal of Intelligent Information Systems  
A transducer model is introduced to compare tree languages (schemas) with different alphabets and attributes.  ...  We use the Edit distance with Moves on words and trees and say that two regular (tree) languages are ε-close if every word (tree) of one language is ε-close to the other.  ...  There is a large literature on tree transducers and our model is close to the top-down tree transducers of [11] , but also handles attributes values.  ...

The time complexity of typechecking tree-walking tree transducers

Joost Engelfriet
2008 Acta Informatica  
Tree-walking tree transducers can be typechecked in double exponential time. More generally, compositions of k tree-walking tree transducers can be typechecked in (k + 1)-fold exponential time.  ...  Consequently k-pebble tree transducers, which form a model of XML transformations and XML queries, can be typechecked in (k + 2)-fold exponential time.  ...  An attribute grammar for which the values of the attributes are trees, i.e., unevaluated expressions, is called an attributed tree transducer (see [7, 8] ).  ...
