Grammar systems are a subfield of Formal Language Theory based on
the use of multiple grammars working in parallel and sharing results
through communication to generate a common language. We focus our
attention on a particular type of grammar system, namely eco-grammar
system, that can be used as a formal framework for modelling multiagent
systems. We present eco-grammar systems not as language generators but
as problem solvers that can adopt LCC protocol to specify the
interactions and cooperation required between agents (grammars)
to
solve problems related with language generation. We plan to study the
possible benefits of this approach.
