AI has become pervasive in recent years, but state-of-the-art approaches predominantly neglect the need for AI systems to be contestable.

Technical Report on the Learning of Case Relevance in Case-Based Reasoning with Abstract Argumentation

no code implementations30 Oct 2023 Guilherme Paulino-Passos, Francesca Toni

Specifically, we show that, for two legal datasets, AA-CBR and decision-tree-based learning of case relevance perform competitively in comparison with decision trees.

On Interactive Explanations as Non-Monotonic Reasoning

no code implementations30 Jul 2022 Guilherme Paulino-Passos, Francesca Toni

To better analyse this issue, in this work we treat explanations as objects that can be subject to reasoning and present a formal model of the interactive scenario between user and system, via sequences of inputs, outputs, and explanations.

Cautious Monotonicity in Case-Based Reasoning with Abstract Argumentation

no code implementations10 Jul 2020 Guilherme Paulino-Passos, Francesca Toni

Recently, abstract argumentation-based models of case-based reasoning ($AA{\text -}CBR$ in short) have been proposed, originally inspired by the legal domain, but also applicable as classifiers in different scenarios, including image classification, sentiment analysis of text, and in predicting the passage of bills in the UK Parliament.
