Simulating processes of concept formation and communication

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 communication in that process is. We consider, in particular, the role of unsupervised learning in the formation of agents' conceptual models, the relative subjectivity of these models, and the communication and learning processes that lead into intersubjective sharing of concepts. We also discuss some implications of the subjectivity of conceptual learning in the area of economics.
