Beyond But-for Test: Counterfactual Explanation in Abstract Argumentation via Actual Causality (Extended Version)
Siyi Liu, Muyun Shao, Beishui Liao
Counterfactual explanation in abstract argumentation calls for an answer to the what-if query: would the topic argument still be accepted if the status of certain other arguments w…
Subargument Argumentation Frameworks: Separating Direct Conflict from Structural Dependency
Beishui Liao
Dung's abstract argumentation frameworks model acceptability solely in terms of an attack relation, thereby conflating two conceptually distinct aspects of argumentative reasoning:…
Enhancing Conflict Resolution in Language Models via Abstract Argumentation
Zhaoqun Li, Xiaotong Fang, Chen Chen +2
In recent years, large language models (LLMs) have made significant advancements in developing human-like and engaging dialogue systems. However, in tasks such as consensus-buildin…
Defense semantics of argumentation: revisit
Beishui Liao, Leendert van der Torre
In this paper we introduce a novel semantics, called defense semantics, for Dung's abstract argumentation frameworks in terms of a notion of (partial) defence, which is a triple en…
What Do You Care About: Inferring Values from Emotions
Jieting Luo, Mehdi Dastani, Thomas Studer +1
Observers can glean information from others' emotional expressions through the act of drawing inferences from another individual's emotional expressions. It is important for social…
A Concept and Argumentation based Interpretable Model in High Risk Domains
Haixiao Chi, Dawei Wang, Gaojie Cui +2
Interpretability has become an essential topic for artificial intelligence in some high-risk domains such as healthcare, bank and security. For commonly-used tabular data, traditio…
Value-based Practical Reasoning: Modal Logic + Argumentation
Jieting Luo, Beishui Liao, Dov Gabbay
Autonomous agents are supposed to be able to finish tasks or achieve goals that are assigned by their users through performing a sequence of actions. Since there might exist multip…
BTPK-based interpretable method for NER tasks based on Talmudic Public Announcement Logic
Yulin Chen, Beishui Liao, Bruno Bentzen +4
As one of the basic tasks in natural language processing (NLP), named entity recognition (NER) is an important basic tool for downstream tasks of NLP, such as information extractio…
A Formal Framework for Reasoning about Agents' Independence in Self-organizing Multi-agent Systems
Jieting Luo, Beishui Liao, John-Jules Meyer
Self-organization is a process where a stable pattern is formed by the cooperative behavior between parts of an initially disordered system without external control or influence. I…
A Bayesian Approach to Direct and Inverse Abstract Argumentation Problems
Hiroyuki Kido, Beishui Liao
This paper studies a fundamental mechanism of how to detect a conflict between arguments given sentiments regarding acceptability of the arguments. We introduce a concept of the in…
Representation, Justification and Explanation in a Value Driven Agent: An Argumentation-Based Approach
Beishui Liao, Michael Anderson, Susan Leigh Anderson
Ethical and explainable artificial intelligence is an interdisciplinary research area involving computer science, philosophy, logic, the social sciences, etc. For an ethical autono…
The Jiminy Advisor: Moral Agreements Among Stakeholders Based on Norms and Argumentation
Beishui Liao, Pere Pardo, Marija Slavkovik +1
An autonomous system is constructed by a manufacturer, operates in a society subject to norms and laws, and interacts with end users. All of these actors are stakeholders affected…
Prioritized Norms in Formal Argumentation
Beishui Liao, Nir Oren, Leendert van der Torre +1
To resolve conflicts among norms, various nonmonotonic formalisms can be used to perform prioritized normative reasoning. Meanwhile, formal argumentation provides a way to represen…
Defense semantics of argumentation: encoding reasons for accepting arguments
Beishui Liao, Leendert van der Torre
In this paper we show how the defense relation among abstract arguments can be used to encode the reasons for accepting arguments. After introducing a novel notion of defenses and…
Formulating Semantics of Probabilistic Argumentation by Characterizing Subgraphs: Theory and Empirical Results
Beishui Liao, Kang Xu, Huaxin Huang
In existing literature, while approximate approaches based on Monte-Carlo simulation technique have been proposed to compute the semantics of probabilistic argumentation, how to im…
