Semantics and Pragmatics of Vague Probability Expressions

By Bernhard Kipper and Anthony Jameson (1994)

Proceedings of the Sixteenth Conference of the Cognitive Science Society, Atlanta, pp. 496–501.

Abstract

Two experiments assessed the membership functions that German speakers assign to 12 adverb phrases and 17 modal verb forms that express probability assessments. These expressions fall largely into three rather homogeneous classes. The membership functions are used as part of the semantic knowledge base of the natural language dialog system PRACMA, one of whose purposes is to model pragmatic and contextual influences on the use of vague expressions. The system’s normative model accounts for the role, in the selection and interpretation of vague probability expressions, of the listener’s prior expectations, the speaker’s dialog motivation, and the expressions that the speaker could have used but did not.
