I use game theory, decision theory, and situation theory to model a class of implicatures. Two types of relevance are distinguished and used to construct a model of Gricean communication between speaker and addressee. 1 I n t r o d u c t i o n Grice's[5] account of nonnatural communication includes as a corollary an account of how more can be communicated than what is saidJ ,Conversely 2, the G...

This process involves constructing and updating the representation of the context. Assertion, implicature and presupposition can be described as three different ways in which changes in the representation of the co...

This article presents evidence that individual words and phrases can contribute multiple independent pieces of meaning simultaneously. Such multidimensionality is a unifying theme of the literature on conventional implicatures and expressives. I use phenomena from discourse, semantic composition, and morphosyntax to detect and explore various dimensions of meaning. I also argue that, while the ...

We explain the relevance of Nash, Hoare and others in explaining Gricean implicature and cheap talk.

Tow models, one qualitative and one quantitative are introduced.

Audience-aware credibility is defined as how bloggers signal their credibility based on who they think their a...
