Abstract

In this paper, after a brief review of current computational models on language emergence, a multi-agent model is introduced to simulate the emergence of a compositional language from a holistic signaling system, through iterative interactions among heterogeneous agents. A coevolution of lexicon and syntax (in the form of simple word order) is tracked during communications with indirect meaning transference, in which the listener’s comprehension is based on interactions of linguistic and nonlinguistic information, and the feedback is not a direct meaning check. In this model, homonymous and synonymous rules emerge inevitably, and a sufficiently developed communication system is available only when a homonym-avoidance mechanism is adopted. In addition, certain degrees of heterogeneity regarding agent’s natural characteristics and linguistic behaviors do not significantly affect language emergence. Finally, based on theories of complex networks, a preliminary study of social structure’s influence on language emergence is given, and a coevolution of the emergence of language and that of simple social structure is implemented.

Keywords: language emergence (phylogenetic), computational modeling, coevolution (lexicon & syntax), coevolution (language & social structure)
