𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻:
Computational argumentation theory provides essential tools for analyzing structured debates, with applications in AI-assisted decision-making systems, online discussion platforms, and human-AI interaction. In this context, explainability is critical: systems must not only determine which arguments are accepted based on abstract semantics, but also make this reasoning transparent and cognitively accessible to human users. Yet, existing semantics—typically grounded in logic-based frameworks and Dung’s abstract argumentation—might fail to align with human intuitions, limiting both their usability and trustworthiness in practice.

This fully funded PhD thesis will focus on improving the alignment between formal acceptability semantics and human reasoning. Research objectives include:
• Evaluating whether current principled constraints are perceived as intuitive by users
• Assessing their explanatory power, particularly in helping users grasp why certain arguments are accepted or rejected
• Formalizing new principles or designing alternative semantics to better capture observed reasoning patterns
• Investigating quantitative impact measures, which capture how much individual arguments influence the acceptability of others, and evaluating how such influence is perceived and interpreted by users

The project is highly interdisciplinary, involving close collaboration with psychologists and cognitive scientists, and combining formal modeling, empirical user studies, and potential software prototypes. The overarching goal is to contribute to the development of more explainable, intuitive, and responsible AI systems, grounded in both logical foundations and empirical validation.

Good level of English is required. Applicants should have a strong background in logic, AI, computer science, or related fields. An interest in cognitive science is welcome.

The PhD includes full funding, collaboration opportunities and publication support.
