Modeling structure-function relationships in synthetic DNA sequences using attribute grammars. [PDF]
Recognizing that certain biological functions can be associated with specific DNA sequences has led various fields of biology to adopt the notion of the genetic part.

Knowledge Representation with Attribute Grammars [PDF]
Summary: The use of attribute grammars for knowledge representation is examined in the present paper. It is shown how data knowledge and knowledge-base knowledge can be represented using syntactic and semantic notation. Control knowledge is represented by the parsing mechanism of the interpreter used.

Interpretation and reduction of attribute grammars [PDF]
An attribute grammar (AG) is in reduced form if in all its derivation trees every attribute contributes to the translation. We prove that, eventhough AG are generally not in reduced form, they can be reduced, i.e., put into reduced form, without modifying their translations. This is shown first for noncircular AG and then for arbitrary AG.

Attribute Grammar Evolution [PDF]
This paper describes Attribute Grammar Evolution (AGE), a new Automatic Evolutionary Programming algorithm that extends standard Grammar Evolution (GE) by replacing context-free grammars by attribute grammars. GE only takes into account syntactic restrictions to generate valid individuals.

An attribute grammar for Ada [PDF]
We describe the development of a formal specification of the static semantics of Ada in form of an attribute grammar. This specification is complete, and was tested extensively with automatically generated equivalent Pascal programs. From this specification we systematically developed the semantic analysis part of our Ada Compiler Front End. We outline

Dynamic Attribute Grammars [PDF]
Although Attribuate Grammars were introduced thirty years ago, their lack of expressiveness has resulted in limited use outside the domain of static language processing. With the new notion of a Dynamic Attribute Grammar defined on a Grammar Couple, informally presented in a previous paper, we show that it is possible to extend this expressiveness and ...

Aspect-Oriented Attribute Grammars
Nepaisant kelių mokslininkų pastangų, skirtų kalbų modulumui tirti, vis tiek islieka kalbos specifikos problema. Pateikiamas formalus požiūris į gerai žinomas programavimo kalbas. Pristatomas naujas kalbos specifikos tyrimas, padidinantis modulumą, pritaikymą, o kartu ir mažinantis kūrėjų pastangas sukurti naują kalbą. Il. 4, bibl.

Grammar-Based Specification and Parsing of Binary File Formats
The capability to validate and view or play binary file formats, as well as to convert binary file formats to standard or current file formats, is critically important to the preservation of digital data and records. This paper describes the extension of

Estimation of stochastic attribute-value grammars using an informative sample [PDF]
We argue that some of the computational complexity associated with estimation of stochastic attribute-value grammars can be reduced by training upon an informative subset of the full training set.

Conditional attribute grammars [PDF]
Attribute grammars are a useful formalism for the specification of computations on structured terms. The classical definition of attribute grammars, however, has no way of treating conditionals nonstrictly. Consequently, the natural way of expressing many otherwise well-behaved computations involves a circularity. This article presents
