Splicing Array Grammar Systems
2005Splicing Array Grammar Systems (SAGS) generating pictures of rectangular arrays of symbols are introduced. The components consist of two-dimensional tabled matrix Grammars working in parallel and arrays generated in two different components of the SAGS are allowed to be “cut” and “pasted” according to array splicing domino rules.

An array grammar programming system
Communications of the ACM, 1973A package of Fortran programs has been developed that permits a user to interactively design and test array grammars. The user can control the rule selection procedure in a derivation or parse, using weighted programming matrices; he also has a choice of instance selection schemes (raster, random, parallel). Examples are given involving array languages

Graph grammars for distributed systems
2005In the paper we define grammars on a class of labeled, partially ordered hypergraphs, called distributed systems. A distributed system models both the spatial and the temporal aspects of a real system through the relations of adjacency and causality. Terminal symbols represent the (deterministic, certain) past history of the system while nonterminal ...

Grammar systems versus membrane computing: the case of CD grammar systems
Fundam. Informaticae, 2007Summary: We discuss some relationships between grammar systems and P systems (membrane systems), two areas of computer science dealing with distributed computing models, but with different motivations and different types of basic ingredients. We extend one of the most important communication protocols of cooperating distributed (CD) grammar systems ...

Grammar model and grammar induction in the system NL PAGE
1998The input to the natural language parser generation system NL PAGE is in the form of an annotated natural language text, which is used to generate a grammar and a lexicon. This paper describes the format of the text, a new grammar model that is used in the system, and the process of grammar induction.

ON METALINEAR PARALLEL COMMUNICATING GRAMMAR SYSTEMS
International Journal of Foundations of Computer Science, 2007A generalization of centralized and returning parallel communicating grammar systems with linear components (linear CPC grammar systems) is studied. It is known that linear CPC grammar systems are more powerful than regular CPC grammar systems and that CPC grammar systems with context-free components are more powerful than linear CPC grammar systems ...

Grammar-Based Definition of Metaprogramming Systems
ACM Transactions on Programming Languages and Systems, 1984Description d'une approche basee sur la grammaire de la specification des composants de manipulation syntactique d'un systeme de meta-programmation. La methode est applicable a tout langage de programmation et est illustree dans son application particuliere au ...

Control Systems on Automata and Grammars
The Computer Journal, 2013This work is primarily inspired by the observation that supervisory control and regulated rewriting have the same nature. Indeed, both of them model a system using some formalism, and use a certain formalized control structure to restrict the behavior of the system via some designated control mechanism.

A System for Archivable Grammar Documentation
2013This paper describes a number of criteria for archivable documentation of grammars of natural languages, extending the work of Bird and Simons’ “Seven dimensions of portability for language documentation and description.” We then describe a system for writing and testing morphological and phonological grammars of languages, a system which satisfies ...
