A computational model of the coevolution of lexicon and syntax

In this paper, a multi-agent computational model is used to simulate the emergence of a compositional language from a holistic signaling system through iterative interactions among heterogeneous agents. Syntax, in the form of simple word order, coevolves with the emergence of the lexicon through self-organization in individuals. We simulate an indirect meaning transference, in which the listener’s comprehension is based on the interaction of linguistic and nonlinguistic information, together with a feedback without direct meaning checking. Homonyms and synonyms emerge inevitably during the rule acquisition. Homonym avoidance is assumed to be a necessary mechanism for developing an effective communication system.
