  1. The Status of Arguments in Abstract Argumentation Frameworks. A Tableaux Method.Gustavo A. Bodanza & Enrique Hernández-Manfredini - 2023 - Manuscrito 46 (2):66-108.
    Dung’s argumentation frameworks are formalisms widely used to model interaction among arguments. Although their study has been profusely developed in the field of Artificial Intelligence, it is not common to see its treatment among those less connected to computer science within the logical-philosophical community. In this paper we propose to bring to that audience a proof-theory for argument justification based on tableaux, very similar to those the Logic students are familiar with. The tableaux enable to calculate whether an argument or (...)

    Two approaches to the problems of self-attacking arguments and general odd-length cycles of attack.Gustavo A. Bodanza & Fernando A. Tohmé - 2009 - Journal of Applied Logic 7 (4):403-420.
    The problems that arise from the presence of self-attacking ar- guments and odd-length cycles of attack within argumentation frameworks are widely recognized in the literature on defeasible argumentation. This paper introduces two simple semantics to capture different intuitions about what kinds of arguments should become justified in such scenarios. These semantics are modeled upon two extensions of argumentation frameworks, which we call sustainable and tolerant. Each one is constructed on the common ground of the powerful concept of admissibility introduced by (...)

    Confronting value-based argumentation frameworks with people’s assessment of argument strength.Gustavo A. Bodanza & Esteban Freidin - 2023 - Argument and Computation 14 (3):247-273.
    We reported a series of experiments carried out to confront the underlying intuitions of value-based argumentation frameworks (VAFs) with the intuitions of ordinary people. Our goal was twofold. On the one hand, we intended to test VAF as a descriptive theory of human argument evaluations. On the other, we aimed to gain new insights from empirical data that could serve to improve VAF as a normative model. The experiments showed that people’s acceptance of arguments deviates from VAF’s semantics and is (...)

    Local logics, non-monotonicity and defeasible argumentation.Gustavo A. Bodanza & Fernando A. Tohmé - 2004 - Journal of Logic, Language and Information 14 (1):1-12.
    In this paper we present an embedding of abstract argumentation systems into the framework of Barwise and Seligmans logic of information flow. We show that, taking P.M. Dungs characterization of argument systems, a local logic over states of a deliberation may be constructed. In this structure, the key feature of non-monotonicity of commonsense reasoning obtains as the transition from one local logic to another, due to a change in certain background conditions. Each of Dungs extensions of argument systems leads to (...)

    Marcos de argumentación: Relacionando principios para la evaluación de las semánticas con juegos de justificación de argumentos.Gustavo Adrián Bodanza - 2023 - Análisis Filosófico 43 (2):223-244.
    Los marcos de argumentación son modelos de argumentación derrotable desarrollados en el campo de la inteligencia artificial para analizar la justificación de argumentos según su interacción por medio de ataques. Las semánticas de extensiones para los marcos de argumentación son criterios para sancionar uno (punto de vista escéptico) o varios (punto de vista crédulo) subconjuntos de argumentos justificados. Una forma de evaluar diferentes semánticas de extensiones es considerando si satisfacen o no algunos “principios” (es decir, propiedades razonables o deseables). Además (...)

    (1 other version)La argumentación abstracta en Inteligencia Artificial: problemas de interpretación y adecuación de las semánticas para la toma de decisiones.Gustavo Adrián Bodanza - 2015 - Theoria: Revista de Teoría, Historia y Fundamentos de la Ciencia 30 (3):395-414.
    El modelo de marcos argumentativos abstractos es actualmente la herramienta más utilizada para caracterizar la justificación de argumentos derrotables en Inteligencia Artificial. Las justificaciones se determinan en base a los ataques entre argumentos y se formalizan a través de semánticas de extensiones. Aquí sostenemos que, o bien algunos marcos argumentativos carecen de sentido bajo ciertas concepciones de ataque específicas, o bien las semánticas más usadas en la literatura, basadas en el concepto de defensa conocido como admisibilidad, no resultan adecuadas para (...)
