[{"content":"Since its inception in 2001, the CMNA workshop series has focused upon the issue of modelling “natural” argumentation, where naturalness may range across a variety of forms, perhaps involving the use of visual rather than linguistic means to illustrate a point, for example using graphics or multimedia, or applying more sophisticated rhetorical devices, interacting at various layers of abstraction, or exploiting \u0026ldquo;extra-rational\u0026rdquo; characteristics of the audience, taking into account emotions and affective factors.\nAI has witnessed a prodigious growth in uses of argumentation throughout many of its subdisciplines:\nagent system negotiation protocols that demonstrate higher levels of sophistication and robustness; argumentation-based models of evidential relations and legal processes that are more expressive; groupwork tools that use argument to structure interaction and debate; computer-based learning tools that exploit monological and dialogical argument structures in designing pedagogic environments; decision support systems that build upon argumentation theoretic models of deliberation to better integrate with human reasoning; and models of knowledge engineering structured around core concepts of argument to simplify knowledge elicitation and representation problems. Furthermore, benefits have not been unilateral for AI, as demonstrated by the increasing presence of AI scholars in classical argumentation theory events and journals, and AI implementations of argument finding application in both research and pedagogic practice within philosophy and argumentation theory.\n","permalink":"https://cmna-workshop.github.io/cmna26/about/","summary":"Since its inception in 2001, the CMNA workshop series has focused upon the issue of modelling “natural” argumentation, where naturalness may range across a variety of forms, perhaps involving the use of visual rather than linguistic means to illustrate a point, for example using graphics or multimedia, or applying more sophisticated rhetorical devices, interacting at various layers of abstraction, or exploiting \u0026ldquo;extra-rational\u0026rdquo; characteristics of the audience, taking into account emotions and affective factors.","title":"About CMNA"},{"content":" Regular Paper submission (long \u0026amp; short papers): 6th July 2026 Notification to authors: 10th August 2026 Demo, position statement, \u0026amp; late breaking results submission (2 page abstract): 14th August 2026 Demo, position statement, \u0026amp; late breaking results Notification to authors: 21st August 2026 Final (Camera Ready) version of all contributions: 31st August 2026 Workshop (exact date to be confirmed): 14-15th September 2026 ","permalink":"https://cmna-workshop.github.io/cmna26/dates/","summary":" Regular Paper submission (long \u0026amp; short papers): 6th July 2026 Notification to authors: 10th August 2026 Demo, position statement, \u0026amp; late breaking results submission (2 page abstract): 14th August 2026 Demo, position statement, \u0026amp; late breaking results Notification to authors: 21st August 2026 Final (Camera Ready) version of all contributions: 31st August 2026 Workshop (exact date to be confirmed): 14-15th September 2026 ","title":"Dates"},{"content":" [2026.04.02] All new CMNA'26 Website published.

We pride ourselves on operating CMNA as a \u0026ldquo;broad church\u0026rdquo; and aiming for inclusiveness so if you\u0026rsquo;re unsure of whether CMNA is a good fit for your work you can:\ncontact a member of the organising committee, or explore our archives at the CMNA.info site or survey a selection of papers from the CEUR archive of previous CMNA workshops: Volume #3769 (CMNA'25), Volume #3769 (CMNA'24), Volume #3614 (CMNA'23), Volume #3205 (CMNA'22), Volume #2937 (CMNA'21), Volume #2269 (CMNA'20), Volume #2346 (CMNA'19), Volume #2048 (CMNA'17), Volume #1876 (CMNA'16) Downloadable Calls for Papers (CFP) This site covers all of the material in the CFP, but if you want a PDF version for offline use, feel free to grab one of these:\nWorkshop Submissions All submission types will be handled by the Conference Management Toolkit (CMT). Please submit your papers, demos, and posters via CMT using the following link:\nWorkshop Categories The workshop encourages submissions spanning a number of categories:\nLong papers, either reporting on completed work or offering a polemic discussion on a burning issue (up to 10 pages). Short papers describing work in progress (up to 5 pages). Demos (2 page abstract describing the demo) Position Statement(2 page abstract establishing a research position). Late breaking results (2 page abstract reporting the results). All submissions may also use as many additional pages as are necessary for references.\nAll accepted submissions will be archived locally on this site. Long \u0026amp; short papers will also be archved through CEUR workshop proceedings. Demos \u0026amp; posters will only be archived locally.\nIt is highly recommended, but not mandatory, to format papers using the CEUR Single Column Style (more details below in the style section).\nContribution Style For final proceedings submission we\u0026rsquo;ll use the CEUR styles specifically the single column style from this page. It is recommended that you prepare your submission for review using this style.\nIf the following don\u0026rsquo;t download automatically then please right click on the required link and select \u0026ldquo;save link as\u0026hellip;\u0026rdquo; from the pop-up menu.\nFor LaTeX users: Use the Overleaf CEUR LaTeX template or download the zip archive for offline LaTeX compilation. For Open Document Format users: ODT Template For Word Users: DOCX Template Pre-Proceedings Publication We\u0026rsquo;ve gotten into the habit recently of publishing pre-proceedings shortly before the workshop so that folk can attend having prepared for the workshop, knowing what to expect, and being ready to engage with the presented work.\nSo we plan to publish proceedings for CMNA 26 through CEUR Workshop Proceedings as has happened in previous years, but should there be a delay, we\u0026rsquo;ll pre-publish papers here for use during the workshop.\n","permalink":"https://cmna-workshop.github.io/cmna26/submission/","summary":"Considering a submission to CMNA?
