More specifically, we study two prominent\n\nalternatives to the standard notion of admissibility from\n\nabstract argumentation, namely strong and weak\n\nadmissibility, and introduce the respective preferred,\n\ncomplete and grounded semantics for general (sometimes\n\ncalled non-flat) ABA. To do so, we use abstract bipolar\n\nset-based argumentation frameworks (BSAFs) as formal\n\nplayground since they concisely capture the relations\n\nbetween assumptions and are expressive enough to represent\n\ngeneral non-flat ABA frameworks, as recently shown. While\n\nweak admissibility has been recently investigated for a\n\nrestricted fragment of ABA in which assumptions cannot be\n\nderived (flat ABA), strong admissibility has not been\n\ninvestigated for ABA so far. We introduce strong\n\nadmissibility for ABA and investigate desirable properties.\n\nWe furthermore extend the recent investigations of weak\n\nadmissibility in the flat ABA fragment to the non-flat case.  We show that the central modularization property is maintained under classical, strong, and weak admissibility. We also show that strong and weakly admissible semantics in non-flat ABA share some of the shortcomings of standard admissible semantics and discuss ways to address these.<\/jats:p>","DOI":"10.24963\/kr.2025\/14","type":"proceedings-article","created":{"date-parts":[[2025,11,5]],"date-time":"2025-11-05T06:10:44Z","timestamp":1762323044000},"page":"137-147","source":"Crossref","is-referenced-by-count":0,"title":["On Strong and Weak Admissibility in Non-Flat Assumption-Based Argumentation"],"prefix":"10.24963","author":[{"given":"Matti","family":"Berthold","sequence":"first","affiliation":[{"name":"ScaDS.AI, Universit\u00e4t Leipzig"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lydia","family":"Bl\u00fcmel","sequence":"additional","affiliation":[{"name":"Artificial Intelligence Group, University of Hagen"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Rapberger","sequence":"additional","affiliation":[{"name":"Imperial College London"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10584","event":{"name":"22nd International Conference on Principles of Knowledge Representation and Reasoning {KR-2025}","theme":"Artificial Intelligence","location":"Melbourne, Australia","acronym":"KR-2025","number":"22","sponsor":["Artificial Intelligence Journal","Principles of Knowledge Representation and Reasoning Inc.","Academic College of Tel-Aviv","European Association for Artificial Intelligence","National Science Foundation"],"start":{"date-parts":[[2025,11,11]]},"end":{"date-parts":[[2025,11,17]]}},"container-title":["Proceedings of the TwentySecond International Conference on Principles of Knowledge Representation and Reasoning"],"original-title":[],"deposited":{"date-parts":[[2025,11,5]],"date-time":"2025-11-05T06:10:56Z","timestamp":1762323056000},"score":1,"resource":{"primary":{"URL":"https:\/\/proceedings.kr.org\/2025\/14"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2025,11]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/kr.2025\/14","relation":{},"subject":[],"published":{"date-parts":[[2025,11]]}}}
