  1. Ivano A. Ciardelli & Floris Roelofsen (forthcoming). Inquisitive Dynamic Epistemic Logic. Synthese:1-45.
    Information exchange can be seen as a dynamic process of raising and resolving issues. The goal of this paper is to provide a logical framework to model and reason about this process. We develop an inquisitive dynamic epistemic logic (IDEL), which enriches the standard framework of dynamic epistemic logic (DEL), incorporating insights from recent work on inquisitive semantics. At a static level, IDEL does not only allow us to model the information available to a set of agents, like standard epistemic (...)

  2. Maria Aloni & Floris Roelofsen (2014). Indefinites in Comparatives. Natural Language Semantics 22 (2):145-167.
    The goal of this paper is to explain the meaning and distribution of indefinites in comparatives, focusing on English some and any and German irgend-indefinites. We consider three competing theories of comparatives in combination with an alternative semantics of some and any, and a novel account of stressed irgend-indefinites. One of the resulting accounts, based on Heim’s analysis of comparatives, predicts all the relevant differences in quantificational force, and explains why free choice indefinites are licensed in comparatives.

  3. Ivano Ciardelli, Jeroen Groenendijk & Floris Roelofsen (2013). On the Semantics and Logic of Declaratives and Interrogatives. Synthese:1-40.
    In many natural languages, there are clear syntactic and/or intonational differences between declarative sentences, which are primarily used to provide information, and interrogative sentences, which are primarily used to request information. Most logical frameworks restrict their attention to the former. Those that are concerned with both usually assume a logical language that makes a clear syntactic distinction between declaratives and interrogatives, and usually assign different types of semantic values to these two types of sentences. A different approach has been taken (...)

  4. Floris Roelofsen (2013). Algebraic Foundations for the Semantic Treatment of Inquisitive Content. Synthese 190 (S1):1-24.
    In classical logic, the proposition expressed by a sentence is construed as a set of possible worlds, capturing the informative content of the sentence. However, sentences in natural language are not only used to provide information, but also to request information. Thus, natural language semantics requires a logical framework whose notion of meaning does not only embody informative content, but also inquisitive content. This paper develops the algebraic foundations for such a framework. We argue that propositions, in order to embody (...)

  5. Maria Aloni & Floris Roelofsen (2011). Interpreting Concealed Questions. Linguistics and Philosophy 34 (5):443-478.
    Concealed questions are determiner phrases that are naturally paraphrased as embedded questions (e.g., John knows the capital of Italy ≈ John knows what the capital of Italy is). This paper offers a novel account of the interpretation of concealed questions, which assumes that an entity-denoting expression α may be type-shifted into an expression ?z.P(α), where P is a contextually determined property, and z ranges over a contextually determined domain of individual concepts. Different resolutions of P and the domain of z (...)

  6. Floris Roelofsen (2011). Inquisitive Logic. Journal of Philosophical Logic 40 (1):55 - 94.
    This paper investigates a generalized version of inquisitive semantics. A complete axiomatization of the associated logic is established, the connection with intuitionistic logic and several intermediate logics is explored, and the generalized version of inquisitive semantics is argued to have certain advantages over the system that was originally proposed by Groenendijk (2009) and Mascarenhas (2009).

  7. Floris Roelofsen (2010). Condition B Effects in Two Simple Steps. Natural Language Semantics 18 (2):115-140.
    This paper is concerned with constraints on the interpretation of pronominal anaphora, in particular Condition B effects. It aims to contribute to a particular approach, initiated by Reinhart (Anaphora and semantic interpretation, 1983) and further developed elsewhere. It proposes a modification of Reinhart’s Interface Rule, and argues that the resulting theory compares favorably with others, while being compatible with independently motivated general hypotheses about the interaction between different interpretive mechanisms.

  8. Floris Roelofsen (2007). Distributed Knowledge. Journal of Applied Non-Classical Logics 17 (2):255-273.
    This paper provides a complete characterization of epistemic models in which distributed knowledge complies with the principle of full communication (van der Hoek et al., 1999; Gerbrandy, 1999). It also introduces an extended notion of bisimulation and corresponding model comparison games that match the expressive power of distributed knowledge operators.
