    An Argumentation-Based Approach for Reasoning About Trust in Information Sources.Leila Amgoud & Robert Demolombe - 2014 - Argument and Computation 5 (2-3):191-215.
    During a dialogue, agents exchange information with each other and need thus to deal with incoming information. For that purpose, they should be able to reason effectively about trustworthiness of information sources. This paper proposes an argument-based system that allows an agent to reason about its own beliefs and information received from other sources. An agent's beliefs are of two kinds: beliefs about the environment and beliefs about trusting sources . Six basic forms of trust are discussed in the paper (...)

    Logical Limits of Abstract Argumentation Frameworks.Leila Amgoud & Philippe Besnard - 2013 - Journal of Applied Non-Classical Logics 23 (3):229 - 267.
    Dung?s (1995) argumentation framework takes as input two abstract entities: a set of arguments and a binary relation encoding attacks between these arguments. It returns acceptable sets of arguments, called extensions, w.r.t. a given semantics. While the abstract nature of this setting is seen as a great advantage, it induces a big gap with the application that it is used to. This raises some questions about the compatibility of the setting with a logical formalism (i.e., whether it is possible to (...)

    Foundations for a Logic of Arguments.Leila Amgoud, Philippe Besnard & Anthony Hunter - 2017 - Journal of Applied Non-Classical Logics 27 (3-4):178-195.
    This paper aims at laying some foundations of a logic of argumentation in which arguments, as well as attacks and supports among arguments are all defined in a unifying formalism. In the latter, an argument is denoted as a pair displaying a reason and a conclusion but no condition is required to hold relating the reason to the conclusion. We introduce a series of inference rules relating arguments and show how the resulting system captures important features of argumentation that hitherto (...)

    Equivalence in Logic-Based Argumentation.Leila Amgoud, Philippe Besnard & Srdjan Vesic - 2014 - Journal of Applied Non-Classical Logics 24 (3):181-208.
    This paper investigates when two abstract logic-based argumentation systems are equivalent. It defines various equivalence criteria, investigates the links between them, and identifies cases where two systems are equivalent with respect to each of the proposed criteria. In particular, it shows that under some reasonable conditions on the logic underlying an argumentation system, the latter has an equivalent finite subsystem, called core. This core constitutes a threshold under which arguments of the system have not yet attained their final status and (...)
