Teams in cooperating grammar systems

Journal of Experimental and Theoretical Artificial Intelligence, 1995
We consider grammar systems in which several components are active at the same moment (a team of components is working).

Multigenerative grammar systems and matrix grammars [PDF]

open access: yesKybernetika, 2010
Summary: Multigenerative grammar systems are based on cooperating context-free grammatical components that simultaneously generate their strings in a rule-controlled or nonterminal-controlled rewriting way, and after this simultaneous generation is completed, all the generated terminal strings are combined together by some common string operations ...

A grammar systems approach to natural language grammar

Linguistics and Philosophy, 2006
Taking as its starting point significant similarities between a formal language model—Grammar Systems—and a grammatical theory—Autolexical Syntax—in this paper we suggest the application of the former to the topic of the latter. To show the applicability of Grammar Systems Theory to grammatical description, we introduce a formal-language-theoretic ...

Cooperating Graph Grammar Systems.

open access: yes, 1999
In this paper the concept of cooperation is introduced into the context of graph grammars. Beside the definition of cooperating graph rewriting systems and beside some general comparisons between generated languages, the NLC and BNLC cooperating graph rewriting systems are studied in detail.

Accepting Grammars and Systems via Context Condition Grammars

J. Autom. Lang. Comb., 1996
We investigate several kinds of regulated rewriting (matrix, ordered, programmed, and variants thereof) and of parallel rewriting mechanisms (Lindenmayer systems, uniformly limited Lindenmayer systems, limited Lindenmayer systems and scattered context grammars) as accepting devices, in contrast with the usual generating mode.

Cooperating grammar systems

1978
A new language generating mechanism is defined. It is derived from a generalization of the two-level substitution mechanism and involves several (incomplete) grammars which communicate with each other by introducing variables for which they have no productions themselves. When the grammars are context-free, this yields an alternative definition for the
