Contribution Functions for Quantitative Bipolar Argumentation Graphs: A Principle-based Analysis

no code implementations16 Jan 2024 Timotheus Kampik, Nico Potyka, Xiang Yin, Kristijonas Čyras, Francesca Toni

We present a principle-based analysis of contribution functions for quantitative bipolar argumentation graphs that quantify the contribution of one argument to another.

Complexity Results and Algorithms for Bipolar Argumentation

no code implementations5 Mar 2019 Amin Karamlou, Kristijonas Čyras, Francesca Toni

Bipolar Argumentation Frameworks (BAFs) admit several interpretations of the support relation and diverging definitions of semantics.

Resolving Conflicts in Clinical Guidelines using Argumentation

no code implementations20 Feb 2019 Kristijonas Čyras, Tiago Oliveira

We advance a structured argumentation formalism for reasoning with conflicting clinical guidelines, patient-specific information and preferences.

Argumentation for Explainable Scheduling (Full Paper with Proofs)

no code implementations13 Nov 2018 Kristijonas Čyras, Dimitrios Letsios, Ruth Misener, Francesca Toni

Specifically, we define argumentative and natural language explanations for why a schedule is (not) feasible, (not) efficient or (not) satisfying fixed user decisions, based on models of the fundamental makespan scheduling problem in terms of abstract argumentation frameworks (AFs).

ABA+: Assumption-Based Argumentation with Preferences

no code implementations10 Oct 2016 Kristijonas Čyras, Francesca Toni

We present ABA+, a new approach to handling preferences in a well known structured argumentation formalism, Assumption-Based Argumentation (ABA).
