The Dialogue Modelling Group carries out research at the interface of computational linguistics, cognitive modelling and artificial intelligence. Its aim is to understand how we use language to communicate with each other in situated environments and how dialogue interaction shapes learning — about the world and about language itself. These are some of the topics the Group works on: Semantics and pragmatics of dialogue phenomena, visually grounded language and visual reasoning, conversational agents and learning from interaction, language variation and change in communities of speakers.
