• Recently, significant strides have been made in the ability of transformer-based chatbots to hold natural conversations. However, despite a growing societal and scientific relevancy, there are few frameworks systematically deriving what it means for a chatbot conversation to be natural. The present work approaches this question through the phenomenon of communicative accommodation/interactive alignment. While there is existing research suggesting that humans adapt communicatively to technologies, the aim of this work is to explore the accommodation of AI-chatbots to an interlocutor. Its research interest is twofold: Firstly, the structural ability of the transformer-architecture to support accommodative behavior is assessed using a frame constructed in accordance with existing accommodationtheories. This results in hypotheses to be tested empirically. Secondly, since effective accommodation produces the same outcomes, regardless of technical implementation, a behavioral experiment is proposed. Existing quantifications of accommodation are reconciled, extended, and modified to apply them to nonhuman-interlocutors. Thus, a measurement scheme is suggested which evaluates textual data from text-only, double-blind interactions between chatbots and humans, chatbots and chatbots and humans and humans. Using the generated human-to-human convergence data as a reference, the degree of artificial accommodation can be evaluated. Accommodation as a central facet of artificial interactivity can thus be evaluated directly against its theoretical paradigm, i.e. human interaction. In case that subsequent examinations show that chatbots effectively do not accommodate, there may be a new form of algorithmic bias, emerging from the aggregate accommodation towards chatbots but not towards humans. Thus, existing, hegemonic semantics could be cemented through chatbot-learning. Meanwhile, the ability to effectively accommodate would render chatbots vastly more susceptible to misuse.
