Abstract This paper investigates whether a group of agents may develop a com­ mon lexicon relating words to situations by a process of self­organization. Each agent independently decides which situations are useful to distin­ guish, based on its experience with the environment. It then starts to associate signals with each situation. The agents adapt their own associ­ ations based on the signals they received from other agents. The system is monitored using measures which reflect the development of the lexi­ cons over time. The result of the distributed activities of the agents is that a coherent shared lexicon emerges linking signals to situations.
Introduction A central aspect of human intelligence is our use of language. The aim of the currently expanding research field of language evolution is to gain insight into principles that may explain the development of language and communication. In this paper we pose the fol­ lowing question: Can a common lexicon be established by a process of self­organization? That is, can a group of agents converge to using the same set of associations between concepts and words? This question has already been addressed for the case where the signals refer to objects and the interactions are organized by appointing a speaker and a hearer in [Steels, 1996a]. In this work however, we study the formation of concepts denoting situations encountered during interaction with the environment. An agent de­ termines which situations to distinguish according to the effects of its actions. Successful communication provides potential benefit to the receiver since it complements the basic sensory data. Both the conceptualization of sensory data and the adaptation of a lexicon which associates signals with situations are investigated in this paper. Agents build up their own ...
