The Special Interest Group on Discourse and Dialogue (SIGDIAL) organizers welcome the submission of special session proposals. We welcome special session proposals on any topic of interest to the discourse and dialogue communities. Topics of interest include, but are not limited to Role of Discourse in NLP Applications, Explainable AI, Evaluation, Annotation, End‐to‐end systems, Vision and Language, and Human-Robot Interaction. A SIGDIAL special session is the length of a regular session at the conference, and may be organized as a poster session, a panel session, a poster session with panel discussion, or an oral presentation session. Special sessions may, at the discretion of the SIGDIAL organizers, be held as parallel sessions. The papers submitted to special sessions are handled by the special session organizers, but for the submitted papers to be in the SIGDIAL proceedings, they have to undergo the same review process as regular papers. The reviewers for the special session papers will be taken from the SIGDIAL program committee itself, taking into account the suggestions of the session organizers, and the program chairs will make acceptance decisions. In other words, special session organizers decide what appears in the session, while the program chairs decide what appears in the proceedings and the rest of the conference program. Submissions Those wishing to organize a special session should prepare a two-page proposal containing: a summary of the topic of the special session; a list of organizers and sponsors; a list of people who may submit and participate in the session; and a requested format (poster/panel/oral session). These proposals should be sent to conference@sigdial.org by the special session proposal deadline. Special session proposals will be reviewed jointly by the general chair and program co‐chairs.
