AixDial will be the 22nd edition of the SemDial workshop series, which aims to bring together researchers working on the semantics and pragmatics of dialogue in fields such as formal semantics and pragmatics, computational linguistics, artificial intelligence, philosophy, psychology, and neuroscience. In 2018 the workshop will be hosted by “Laboratoire Parole et Langage” (Aix Marseille Université & CNRS), in its Aix-en-Provence city center location. We invite submissions on all topics related to the semantics and pragmatics of dialogue. See the call for papers for additional information about the scope, topic and format of the workshop and our submission site for instructions to prepare and submit an anonymous full paper for presentation at AixDial.
