Empirical pattern: Scalar implicatures in DE contexts.

In upward-entailing (UE) contexts, "some" implicates "not all". In downward-entailing (DE) contexts, this implicature is blocked.

Examples:

  • UE: "John ate some cookies" → "not all cookies"
  • DE: "No one ate some cookies" → no "not all" implicature
  • ueExample : String

    Example in UE context

  • deExample : String

    Example in DE context

  • scalarTerm : String

    Scalar term used

  • strongerAlt : String

    Stronger alternative on the scale

  • implicatureInUE : Bool

    Does the implicature arise in UE?

  • implicatureInDE : Bool

    Does the implicature arise in DE?

                Empirical pattern: Weak vs strong implicatures.

                From "some students came":

                • Weak: Speaker doesn't believe all came (¬Bel_S(all))
                • Strong: Speaker believes not all came (Bel_S(¬all))

                The strong requires a competence assumption.
