Claim-augmented argumentation frameworks (CAFs) have been introduced to deploy a conclusion-oriented perspective. CAFs expand argumentation frameworks by an additional step which involves retaining claims for an accepted set of arguments. We introduce a novel concept of a justification status for claims, a quantitative measure of extensions supporting a particular claim. The well-studied problems of credulous and skeptical reasoning can then be seen as simply the two endpoints of the spectrum when considered as a justification level of a claim. Furthermore, we explore the parameterized complexity of various reasoning problems for CAFs, including the quantitative reasoning for claim assertions. We begin by presenting a suitable graph representation that includes arguments and their associated claims. Our analysis includes the parameter treewidth, and we present decomposition-guided reductions between reasoning problems in CAF and the validity problem for QBF.</jats:p>"}],"department":[{"_id":"574"}],"type":"conference","language":[{"iso":"eng"}],"publisher":"International Joint Conferences on Artificial Intelligence Organization","user_id":"99353","publication_status":"published","author":[{"first_name":"Johannes K.","last_name":"Fichte","full_name":"Fichte, Johannes K."},{"first_name":"Markus","full_name":"Hecher, Markus","last_name":"Hecher"},{"full_name":"Mahmood, Yasir","last_name":"Mahmood","id":"99353","first_name":"Yasir"},{"first_name":"Arne","full_name":"Meier, Arne","last_name":"Meier"}],"title":"Quantitative Reasoning and Structural Complexity for Claim-Centric Argumentation","year":"2023"}
