  1. A Meta-model of Access Control in a Fibred Security Language.Steve Barker, Guido Boella, Dov M. Gabbay & Valerio Genovese - 2009 - Studia Logica 92 (3):437-477.
    The issue of representing access control requirements continues to demand significant attention. The focus of researchers has traditionally been on developing particular access control models and policy specification languages for particular applications. However, this approach has resulted in an unnecessary surfeit of models and languages. In contrast, we describe a general access control model and a logic-based specification language from which both existing and novel access control models may be derived as particular cases and from which several approaches can be (...)

  • 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 (...)

    We present a logic to model the behaviour of an agent trusting or not trusting messages sent by another agent. The logic formalises trust as a consistency checking function with respect to currentl...

  • A modal type theory for formalizing trusted communications.Giuseppe Primiero & Mariarosaria Taddeo - 2012 - Journal of Applied Logic 10 (1):92-114.
    This paper introduces a multi-modal polymorphic type theory to model epistemic processes characterized by trust, defined as a second-order relation affecting the communication process between sources and a receiver. In this language, a set of senders is expressed by a modal prioritized context, whereas the receiver is formulated in terms of a contextually derived modal judgement. Introduction and elimination rules for modalities are based on the polymorphism of terms in the language. This leads to a multi-modal non-homogeneous version of a (...)

  • Dynamic epistemic logic of belief change in legal judgments.Pimolluck Jirakunkanok, Katsuhiko Sano & Satoshi Tojo - 2018 - Artificial Intelligence and Law 26 (3):201-249.
    This study realizes belief/reliability change of a judge in a legal judgment by dynamic epistemic logic. A key feature of DEL is that possibilities in an agent’s belief can be represented by a Kripke model. This study addresses two difficulties in applying DEL to a legal case. First, since there are several methods for constructing a Kripke model, our question is how we can construct the model from a legal case. Second, since this study employs several dynamic operators, our question (...)

  • A Logic Of Trust And Reputation.Andreas Herzig, Emiliano Lorini, Jomi Hübner & Laurent Vercouter - 2010 - Logic Journal of the IGPL 18 (1):214-244.
    The aim of this paper is to present a logical framework in which the concepts of trust and reputation can be formally characterized and their properties studied. We start from the definition of trust proposed by Castelfranchi & Falcone . We formalize this definition in a logic of time, action, beliefs and choices. Then, we provide a refinement of C&F’s definition by distinguishing two general types of trust: occurrent trust and dispositional trust. In the second part of the paper we (...)

  • Formal reconstruction of notions of belief, utterance and trust.Robert Piechowicz - 2020 - Philosophical Problems in Science 68:63-77.
    Problem of epistemic activity and their relationship with language is very well known in philosophy. Undertaking this challenge in this article we shall present some logical constructions apparent in these issues. More precisely we want to describe some difficulties of formal reconstruction of the notion of belief and utterance and try to find broader perspective appointed by notion of trust. To realize this goals article shows how non-formal assumption about doxa affects on its formal construction. Then, logic of utterances—mainly based (...)
