Discontinuity-Free Decision Support with Quantitative Argumentation Debates
TLDR
A novel, discontinuity-free algorithm for computing the strength of decision options in QuAD frameworks is proposed and it is proved that this algorithm features several desirable properties and is compared to the two aggregation methods, showing that both may be appropriate in the context of different application scenarios. Expand
Quantitative Argumentation Debates with Votes for Opinion Polling
TLDR
A method integrating argumentation within opinion polling to empower voters to add new statements that render their opinions in the polls individually rational while at the same time justifying them is given. Expand
How Many Properties Do We Need for Gradual Argumentation?
TLDR
This paper identifies groups of conceptually related properties in the literature which can be regarded as based on common patterns and evidence that many further properties can be considered, and provides a simplifying and unifying perspective for these properties by showing that they are all implied by the parametric principles of balance and monotonicity.

Argumentation-Based Recommendations: Fantastic Explanations and How to Find Them
TLDR
This work proposes a hybrid method for calculating predicted ratings, built upon an item/aspect-based graph with users’ partially given ratings, that can be naturally used to provide explanations for recommendations, extracted from user-tailored Tripolar Argumentation Frameworks (TFs). Expand
Extracting Dialogical Explanations for Review Aggregations with Argumentative Dialogical Agents
TLDR
A novel form of argumentative dialogical agent (ADA) for explaining the reasoning within the reviews, which provides a dialectical strength which is comparable with the TS, while at the same time being able to provide dialogical explanations of why a movie obtained its strength via interactions between the user and ADA. Expand
Abstract Games of Argumentation Strategy and Game-Theoretical Argument Strength
TLDR
It is shown that this general scheme captures as a special instance a previous proposal in the literature (single agenda, attack-only frameworks), and seamlessly supports the definition of a spectrum of novel measures of game-theoretic strength where both players have an agenda and/or bipolar frameworks are considered. Expand
The "Games of Argumentation" Web Platform
This demo presents the web system “Games of Argumentation”, which allows users to build argumentation graphs and examine them in a game-theoretical manner using up to three different evaluationExpand
From formal argumentation to conversational systems
TLDR
This work considers one such argumentation-empowered conversational system and exemplifies its use and benefits in two different domains, for recommending movies and hotels based on the aggregation of information drawn from reviews. Expand
From fine-grained properties to broad principles for gradual argumentation: A principled spectrum
TLDR
This paper identifies groups of conceptually related properties in the literature which can be regarded as based on common patterns and evidence that many further novel properties can be considered, and provides a simplifying and unifying perspective for these groups of properties. Expand
Relation-Based Counterfactual Explanations for Bayesian Network Classifiers
TLDR
It is proved empirically for various BCs that CFXs provide useful information in real world settings, and it is shown that they have inherent advantages over existing explanation methods in the literature. Expand
