Outline of Final Research Achievements

We proposed an agent-based model for language contact, where we employed Kirby’s iterated learning model (ILM) and complex networks. Totally, we succeeded to implement a linguistic community with learning agents connected with a social network. The network model makes it possible to observe not only diachronic but also synchronic changes in grammar. We achieved implementation of a large-scale, agent-based model where 100 processes of ILM run in parallel, which contributes to the simulation study on language evolution.
