  1. Two Switches in the Theory of Counterfactuals: A Study of Truth Conditionality and Minimal Change.Ivano Ciardelli, Linmin Zhang & Lucas Champollion - 2018 - Linguistics and Philosophy (6).
    Based on a crowdsourced truth value judgment experiment, we provide empirical evidence challenging two classical views in semantics, and we develop a novel account of counterfactuals that combines ideas from inquisitive semantics and causal reasoning. First, we show that two truth-conditionally equivalent clauses can make different semantic contributions when embedded in a counterfactual antecedent. Assuming compositionality, this means that the meaning of these clauses is not fully determined by their truth conditions. This finding has a clear explanation in inquisitive semantics: (...)

  2. Breaking de Morgan's Law in Counterfactual Antecedents.Lucas Champollion, Ivano Ciardelli & Linmin Zhang - manuscript
    The main goal of this paper is to investigate the relation between the meaning of a sentence and its truth conditions. We report on a comprehension experiment on counterfactual conditionals, based on a context in which a light is controlled by two switches. Our main finding is that the truth-conditionally equivalent clauses (i) "switch A or switch B is down" and (ii) "switch A and switch B are not both up" make different semantic contributions when embedded in a conditional antecedent.

    The Semantics of Comparatives: A Difference-Based Approach.Linmin Zhang & Jia Ling - 2021 - Journal of Semantics 38 (2):249-303.
    Degree semantics has been developed to study how the meanings of measurement and comparison are encoded in natural language. Within degree semantics, this paper proposes a difference-based approach to analyze the semantics of comparatives. The motivation is the measurability and comparability of differences involved in comparatives. The main claim is that comparatives encode a subtraction equation among three scalar values: two measurements along an interval scale and the difference between them. We contribute two innovations: using interval arithmetic to implement subtraction, (...)
