Abstract
In this work we study on a 2D square lattice a recent version of the
Naming Game, an agent-based model used for describing the emergence of
linguistic structures. The system is open-ended and agents can invent
new words throughout the evolution of the game, picking them up from a
pool characterised by a Gaussian distribution with standard deviation
sigma. The model displays a nonequilibrium phase transition at a
critical point sigma(c) approximate to 25.6, which separates an
absorbing consensus state from an active fragmented state where agents
continuously exchange different words. The finite-size scaling analysis
of our simulations strongly suggests that the phase transition is
discontinuous.
