Norm Identification through Plan Recognition

no code implementations6 Oct 2020 Nir Oren, Felipe Meneguzzi

Societal rules, as exemplified by norms, aim to provide a degree of behavioural stability to multi-agent societies.

Representing Pure Nash Equilibria in Argumentation

no code implementations19 Jun 2020 Bruno Yun, Srdjan Vesic, Nir Oren

In this paper we describe an argumentation-based representation of normal form games, and demonstrate how argumentation can be used to compute pure strategy Nash equilibria.

Preference Elicitation in Assumption-Based Argumentation

no code implementations12 May 2020 Quratul-ain Mahesar, Nir Oren, Wamberto W. Vasconcelos

Various structured argumentation frameworks utilize preferences as part of their standard inference procedure to enable reasoning with preferences.

Landmark-Based Approaches for Goal Recognition as Planning

no code implementations26 Apr 2019 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.

Using Sub-Optimal Plan Detection to Identify Commitment Abandonment in Discrete Environments

no code implementations26 Apr 2019 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 goals for each other.

Delegating via Quitting Games

no code implementations20 Apr 2018 Juan Afanador, Nir Oren, Murilo S. Baptista

Delegation allows an agent to request that another agent completes a task.

Multi-Armed Bandits

Prioritized Norms in Formal Argumentation

no code implementations23 Sep 2017 Beishui Liao, Nir Oren, Leendert van der Torre, Serena Villata

To resolve conflicts among norms, various nonmonotonic formalisms can be used to perform prioritized normative reasoning.

On the links between argumentation-based reasoning and nonmonotonic reasoning

no code implementations13 Jan 2017 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 nature of argument based reasoning.

Subjective Logic Operators in Trust Assessment: an Empirical Study

no code implementations19 Nov 2013 Federico Cerutti, Alice Toniolo, Nir Oren, Timothy J. Norman

Computational trust mechanisms aim to produce trust ratings from both direct and indirect information about agents' behaviour.

Reasoning about the Impacts of Information Sharing

no code implementations19 Nov 2013 Chatschik Bisdikian, Federico Cerutti, Yuqing Tang, Nir Oren

In this paper we describe a decision process framework allowing an agent to decide what information it should reveal to its neighbours within a communication graph in order to maximise its utility.
