    A Semantics for Hyperintensional Belief Revision Based on Information Bases.Sena Bozdag - 2022 - Studia Logica 110 (3):679-716.
    I propose a novel hyperintensional semantics for belief revision and a corresponding system of dynamic doxastic logic. The main goal of the framework is to reduce some of the idealisations that are common in the belief revision literature and in dynamic epistemic logic. The models of the new framework are primarily based on potentially incomplete or inconsistent collections of information, represented by situations in a situation space. I propose that by shifting the representational focus of doxastic models from belief sets (...)

    Consistency-Sensitive Epistemic Modalities in Information-Based Semantics.Vít Punčochář, Marta Bílková, Sena Bozdag & Thomas M. Ferguson - forthcoming - Studia Logica:1-39.
    The paper extends a framework of information-based semantics for intuitionistic logic with a paraconsistent negation and consistency-sensitive epistemic modalities. In this framework information states represent information collected from various sources and as such they can be inconsistent because they receive contradictory information either from a single inconsistent source or from various mutually incompatible sources. The modalities reflect only those sources that are consistent and trusted. For the paraconsistent logic generated by this framework, we present a Hilbert style system, we prove (...)

    Taking Up Thagard’s Challenge: A Formal Model of Conceptual Revision.Sena Bozdag & Matteo De Benedetto - 2022 - Journal of Philosophical Logic 51 (4):791-824.
    Thagard presented a framework for conceptual change in science based on conceptual systems. Thagard challenged belief revision theorists, claiming that traditional belief-revision systems are able to model only the two most conservative types of changes in his framework, but not the more radical ones. The main aim of this work is to take up Thagard’s challenge, presenting a belief-revision-like system able to mirror radical types of conceptual change. We will do that with a conceptual revision system, i.e. a belief-revision-like system (...)
