Troubles and Failures in Interactional Language. Towards a Linguistically Informed Taxonomy

The goal of this talk is to introduce a systematic research agenda which aims to understand the nature of interaction between humans and artificial conversational agents (CA) (henceforth humanmachine interaction, HMI). Specifically, we shall take an explicit linguistic perspective focusing on linguistically defined variables that are known to influence the flow of conversations among humans (henceforth human-human interaction, HHI).
