An Object Grammar for Column-Convex Polyominoes

Annals of Combinatorics, 2004
In this paper we propose an object grammar decomposition for the classes of columnconvex, and directed column-convex polyominoes. As a consequence, we obtain the enumeration of such classes according to the semi-perimeter, thus giving a natural explanation of the fact that the generating functions of both the classes are algebraic.

Objective evaluation of inferred context-free grammars [PDF]

Proceedings of ANZIIS '94 - Australian New Zealnd Intelligent Information Systems Conference, 2002
An infinite number of context-free grammars may be inferred from a given training set. The defensibility of any single grammar hinges on the ability to compare that grammar against others in a meaningful way. In keeping with the minimum description length principle, smaller grammars are preferred over larger ones, but only insofar as the small grammar ...

Processing Learning Objects with Attribute Grammars

2009 Ninth IEEE International Conference on Advanced Learning Technologies, 2009
The services provided by learning object repositories are usually enabled by the processing of the metadata documents associated with these learning objects. This paper proposes a way to process these metadata documents, which are usually encoded in XML, through a framework called XLOP.

Object-orientation in attribute grammars [PDF]

, 1991
Object-orientation is a language design and programming paradigm aiming at better structuring, reusing, and maintaining properties of software. This paradigm has been successfully combined with conventional programming languages, as well as with functional and logic programming languages; it seems obvious that object-orientation has come to stay ...

Verifying Object-based Graph Grammars

Software & Systems Modeling, 2006
The development of concurrent and reactive systems is gaining importance since they are well-suited to modern computing platforms, such as the Internet. However, the development of correct concurrent and reactive systems is a non-trivial task. Object-based graph grammar (OBGG) is a visual formal language suitable for the specification of this class of ...

Theology as Grammar: Is God an Object of Understanding?

Religious Studies, 1975
i. In the Philosophical Investigations, Ludwig Wittgenstein yoked together these remarks:Essence is expressed by grammar.Grammar tells what kind of object anything is. (Theology as grammar) (Inv. I, 373).

A Grammar-Based Framework for Object Dynamics

1992
A grammar-based categorization of practical systems for modeling the dynamic behaviour of objects is presented. A framework based on Augmented Transition Networks is proposed as an ideal modeling tool for such systems, affording both formal analyzability and the functionality needed to model practical systems.

Derivations in Object-Oriented Graph Grammars

2004
This work aims to extend the algebraic single-pushout approach to graph transformation to model object-oriented systems structures and computations. Graphs whose sets of nodes and edges are partially ordered are used to model the class hierarchy of an object-oriented system, making the inheritance and overriding relations explicit.

Grammars as objects of knowledge: the availability of dispositionalism

Language Sciences, 2002
An anti-dispositionalist interpretation of grammatical knowledge would maintain that such knowledge exists whether or not it can be behaviourally manifested; a dispositionalist interpretation, on the other hand, would identify that knowledge with the in principle possibility of certain behavioural manifestations. The purpose of this paper is to present

Formal Grammar Theory in Recognition Methods of Unknown Objects

Automatic Documentation and Mathematical Linguistics, 2020
Questions on the formation of contextual grammars that describe both the structural information of an image and the interaction of images in a complex scenario have been considered. The use of a multilevel grammar is proposed, including the task of parsing a sequence of images, as well as the task of parsing objects for various purposes, when the ...
