Flash presentation - Argument mining in political debates

Abstract: Argument mining aims to automatically identify and structure argumentative components such as claims and premises within text. Political debates provide a particularly rich but challenging benchmark, as they feature diverse rhetorical strategies, interruptions, and persuasive language. Applying argument mining to this domain enables fine-grained analysis of how political actors justify positions, respond to counter-arguments, and frame issues. In this talk, we will define what argument mining is, demonstrate how to identify claims, premises, relationships, and fallacies in political arguments, and outline future developments.

Generalization of Single-Linkage with Higher-Order Interactions

Abstract: Our goal is to cluster data in Euclidean space. Starting from a statistical model that targets high-density clusters, we recover the classical graph-based method, Single-Linkage (today's state-of-the-art HDBSCAN can be seen as a refinement of Single-Linkage). We then show its natural generalization: build a hypergraph on the data to capture higher-order interactions.
The downside is an apparent combinatorial blow-up; we exploit Euclidean geometry to tackle this problem and show practical cases on large-scale datasets.

Ontology-Driven Interfaces for Spatio-Temporal Exploration of Cultural Landscapes

Abstract: In digital systems, landscapes are often reduced to aesthetic backgrounds or descriptive coordinates, though they embed fundamental narrative and knowledge dimensions. Landscapes are the place for events and shape their meaning, later becoming sites of memories and culture. Investigating and representing the relationships between the landscapes and their multiple layers of significance can improve the effectiveness of territorial management, cultural tourism, historical research, and heritage studies. Digital twins and interactive maps, augmented with the chronological dimension, support the exploration of the themes and the functions of landscape places and objects, relying on documentary sources. An ontology-based approach provides the structural backbone for describing and accessing the knowledge about landscapes and the interactive interface exhibits the augmented landscape as a living and dynamic element of culture.
