Apologies for x-postings CfP: Reasoning and Interaction Conference (ReInAct), University of Gothenburg, Sweden, October 4-6, 2021 (hybrid online and physical event) Reasoning and Interaction (ReInAct) is a conference organized by the Centre for Linguistic Theory and Studies in Probability (CLASP), https://gu-clasp.github.io/ <https://gu-clasp.github.io/>, at the Department of Philosophy, Linguistics and Theory of Science (FLoV), http://flov.gu.se/english <http://flov.gu.se/english>. It is sponsored by SIGSEM http://sigsem.org <http://sigsem.org/>, the ACL special interest group on semantics. The ReInAct conference proceedings will be published online in the ACL Anthology for 2021 as a SIGSEM workshop event. ReInAct will bring together researchers interested in computationally relevant approaches to reasoning and interaction in natural language. ReInAct is open to Machine Learning, Symbolic and Experimental approaches, as well as combinations of these. ReInAct will also involve a shared task on Dialogue Natural Language Inference (DNLI). More details on the task will be published in due course and will be announced here: https://sites.google.com/view/reinact2021/shared-task <https://sites.google.com/view/reinact2021/shared-task> Topics of interest We welcome all computational and/or computationally relevant approaches to reasoning and interaction in natural language. Papers are invited on topics in these and closely related areas, including (but not limited to) the following: * visual, dialogue and multi-modal inference systems * neurolinguistic and psycholinguistic experimental approaches to reasoning and interaction * dialogue modelling and linguistic interaction * formal approaches to social meaning * statistical, machine learning and information theoretic approaches to reasoning and interaction * methodologies and practices for annotating dialogue and multi-modal datasets * formal aspects of reasoning and interaction * visual, dialogue and multi-modal generation * semantics and pragmatics of dialogue acts * multimodal and grounded approaches to computing meaning * semantics-pragmatics interface * applications of visual, dialogue and multi-modal system technology Submission Requirements ReInAct2021 will feature three types of submissions: long papers, student papers, and short papers. All types of papers should be submitted not later than August the 6th August the 17th Long papers must describe original research, and they must not exceed 8 pages excluding references. They will be presented at the conference either orally or as posters. Student papers describe original research, and the first author must be a student, or at least 2/3 of the work on a paper should be done by students. Student papers must not exceed 6 pages excluding references. Reviewers will give special support to student authors through mentoring. The papers will be presented orally or as posters at the conference. Short papers present work in progress, or they describe systems and/or projects. They must not exceed 4 pages excluding references. They will be presented as posters at the conference and summarised in lightning talks. Position papers are also accepted. These should be formatted in the same way as long papers. All types of papers will be published in the conference proceedings in the ACL Anthology. Submissions should be pdf files and use the Latex or Word templates provided for ACL 2021 submissions. <https://2021.aclweb.org/downloads/acl-ijcnlp2021-templates.zip> An overleaf template can be found here <https://www.overleaf.com/latex/templates/instructions-for-acl-ijcnlp-2021-proceedings/mhxffkjdwymb>.Submissions have to be anonymous. Papers should be electronically submitted in PDF format via the softconf system at: https://www.softconf.com/l/reinact2021 <https://www.softconf.com/l/reinact2021>. Please make sure that you select the right track when submitting your paper. Contact the organisers if you have problems using softconf.
