Consequence of reputation in an open-ended Naming Game

TL;DR

This paper investigates how reputation-based hierarchies and external word exchanges affect the dynamics and efficiency of a Naming Game model that simulates the spontaneous emergence of shared vocabulary.

Contribution

It introduces a reputation-influenced strategy and external word interactions into the Naming Game, analyzing their effects on convergence and cognitive effort.

Findings

Reputation influences convergence times

External word exchange impacts memory and time scaling

Hierarchical structures alter the dynamics of vocabulary formation

Abstract

We study a modified version of the Naming Game, a recently introduced model which describes how shared vocabulary can emerge spontaneously in a population without any central control. In particular, we introduce a new mechanism that allows a continuous interchange with the external inventory of words. A novel playing strategy, influenced by the hierarchical structure that individuals' reputation defines in the community, is implemented. We analyze how these features influence the convergence times, the cognitive efforts of the agents and the scaling behavior in memory and time.
