Evaluation of Human-Understandability of Global Model Explanations using Decision Tree
Adarsa Sivaprasad, Ehud Reiter, Nava Tintarev +1
In explainable artificial intelligence (XAI) research, the predominant focus has been on interpreting models for experts and practitioners. Model agnostic and local explanation app…
Inferring Attack Relations for Gradual Semantics
Nir Oren, Bruno Yun
A gradual semantics takes a weighted argumentation framework as input and outputs a final acceptability degree for each argument, with different semantics performing the computatio…
Utility Functions for Human/Robot Interaction
Bruno Yun, Nir Oren, Madalina Croitoru
In this paper, we place ourselves in the context of human robot interaction and address the problem of cognitive robot modelling. More precisely we are investigating properties of…
Analytical Solutions for the Inverse Problem within Gradual Semantics
Nir Oren, Bruno Yun, Assaf Libman +1
Gradual semantics within abstract argumentation associate a numeric score with every argument in a system, which represents the level of acceptability of this argument, and from wh…
The Inverse Problem for Argumentation Gradual Semantics
Nir Oren, Bruno Yun, Srdjan Vesic +1
Gradual semantics with abstract argumentation provide each argument with a score reflecting its acceptability, i.e. how "much" it is attacked by other arguments. Many different gra…
Norm Identification through Plan Recognition
Nir Oren, Felipe Meneguzzi
Societal rules, as exemplified by norms, aim to provide a degree of behavioural stability to multi-agent societies. Norms regulate a society using the deontic concepts of permissio…
Landmark-Based Approaches for Goal Recognition as Planning
Ramon Fraga Pereira, Nir Oren, Felipe Meneguzzi
The task of recognizing goals and plans from missing and full observations can be done efficiently by using automated planning techniques. In many applications, it is important to…
Using Sub-Optimal Plan Detection to Identify Commitment Abandonment in Discrete Environments
Ramon Fraga Pereira, Nir Oren, Felipe Meneguzzi
Assessing whether an agent has abandoned a goal or is actively pursuing it is important when multiple agents are trying to achieve joint goals, or when agents commit to achieving g…
Delegating via Quitting Games
Juan Afanador, Nir Oren, Murilo S. Baptista
Delegation allows an agent to request that another agent completes a task. In many situations the task may be delegated onwards, and this process can repeat until it is eventually,…
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…
On the links between argumentation-based reasoning and nonmonotonic reasoning
Zimi Li, Nir Oren, Simon Parsons
In this paper we investigate the links between instantiated argumentation systems and the axioms for non-monotonic reasoning described in [9] with the aim of characterising the nat…
Context-dependent Trust Decisions with Subjective Logic
Federico Cerutti, Alice Toniolo, Nir Oren +1
A decision procedure implemented over a computational trust mechanism aims to allow for decisions to be made regarding whether some entity or information should be trusted. As reco…
