Simulating processes of concept formation and communication
Journal of Economic Methodology 15(3):245--259, 2008
We propose a theoretical framework for modeling communication between agents that have different conceptual models of their current context. We describe how the emergence of subjective models of the world can be simulated and what the role of language and ...

In this article, we study the emergence of associations between words and concepts using the self-organizing map. In particular, we explore the meaning negotiations among communicating agents. The self-organizing map is used as a model of an agent's conceptual memory. The concepts are not explicitly given but they are learned by the agent in an unsupervised manner. Concepts are viewed as areas formed in a self-organizing map based on unsupervised learning. The language acquisition process is modeled in a population of simulated agents by using a series of language games, specifically observational games. The results of the simulation experiments verify that the agents learn to communicate successfully and a shared lexicon emerges.
