Artificial languages are languages of a typically very limited size which emerge either in computer simulations between artificial agents, robot interactions or controlled psychological experiments with humans. They are different from both constructed languages and formal languages in that they have not been consciously devised by an individual or group but are the result of (distributed) conventionalisation processes, much like natural languages. Opposed to the idea of a central designer, the field of artificial language evolution in which artificial languages are studied can be regarded as a sub-part of the more general cultural evolution studies.

Motivation

The lack of empirical evidence in the field of evolutionary linguistics has led many researchers to adopt computer simulations as a means to investigate the ways in which artificial agents can self-organize languages with natural-like properties. This research is based on the hypothesis that natural language is a complex adaptive system that emerges through interactions between individuals and continues to evolve in order to remain adapted to the needs and capabilities of its users. By explicitly building all assumptions into computer simulations, this strand of research strives to experimentally investigate the dynamics underlying language change as well as questions regarding the origin of language under controlled conditions.
