• Abstract: In many real-life situations that involve exchanges of arguments, individuals may differ on their assessment of which supports between the arguments are in fact justified, i.e., they put forward different support-relations. When confronted with such situations, we may wish to aggregate individuals' argumentation views on support-relations into a collective view, which is acceptable to the group. In this paper, we assume that under bipolar argumentation frameworks, individuals are equipped with a set of arguments and a set of attacks between arguments, but with possibly different support-relations. Using the methodology in social choice theory, we analyze what semantic properties of bipolar argumentation frameworks can be preserved by aggregation rules during the aggregation of support-relations.

• A Methodology for Gradual Semantics for Structured Argumentation under Incomplete Information [15.717458041314194]
  We provide a novel methodology for obtaining gradual semantics for structured argumentation frameworks. Our methodology accommodates incomplete information about arguments' premises. We demonstrate the potential of our approach by introducing two different instantiations of the methodology.

  We present a novel dataset covering demographic and socio-cultural (socio) variables, such as age, gender, and political attitude, representing minority and majority groups in society. We find substantial challenges in incorporating perspectivism, especially when aiming for personalization based solely on the text of arguments without explicitly providing socio profiles. While we bootstrap perspective argument retrieval, further research is essential to optimize retrieval systems to facilitate personalization and reduce polarization.

  We present a novel framework, which uses an Inductive Logic Programming approach to learn the acceptability semantics for several abstract and structured argumentation frameworks in an interpretable way. Our framework outperforms existing argumentation solvers, thus opening up new future research directions in the area of formal argumentation and human-machine dialogues.

• Semi-Abstract Value-Based Argumentation Framework [0.0]
  Phan Minh Dung proposed abstract argumentation framework, which models argumentation using directed graphs where structureless arguments are the nodes and attacks among the arguments are the edges. This thesis showcases two such extensions -- value-based argumentation framework by Trevor Bench-Capon (2002) and semi-abstract argumentation framework by Esther Anna Corsi and Christian Ferm" The contribution of this thesis is two-fold. Firstly, the new semi-abstract value-based argumentation framework is introduced. This framework maps propositional formulae associated with individual arguments to a set of ordered values.

• Some Options for Instantiation of Bipolar Argument Graphs with Deductive Arguments [4.111899441919164]
  A bipolar argument graph is a directed graph where each node denotes an argument, and each arc denotes the influence of one argument on another. In a bipolar argument graph, each argument is atomic and so it has no internal structure. This paper presents a framework based on the use of logical arguments to instantiate bipolar argument graphs.

  We use a novel semantic approach to achieve decidability. Specifically, we augment the logic of knowledge S5$_n$ and with an interaction axiom called (knowledge) commutativity. We prove that our framework admits a finitary non-fixpoint characterization of common knowledge, which is of independent interest.

  This paper empirically shows that the discourse relations between two arguments along the context path are essential factors for identifying the persuasive power of an argument. We propose DisCOC to inject and fuse the sentence-level structural information with contextualized features derived from large-scale language models.

  We train a language model for argument generation that can be controlled on a fine-grained level to generate sentence-level arguments for a given topic, stance, and aspect. Our evaluation shows that our generation model is able to generate high-quality, aspect-specific arguments. These arguments can be used to improve the performance of stance detection models via data augmentation and to generate counter-arguments.

• The Role of Pragmatic and Discourse Context in Determining Argument Impact [39.70446357000737]
  This paper presents a new dataset to initiate the study of this aspect of argumentation. It consists of a diverse collection of arguments covering 741 controversial topics and comprising over 47,000 claims. We propose predictive models that incorporate the pragmatic and discourse context of argumentative claims and show that they outperform models that rely on claim-specific linguistic features for predicting the perceived impact of individual claims within a particular line of argument.
