ACL ID P90-1012
Title Normal State Implicature
Venue Annual Meeting of the Association of Computational Linguistics
Session Main Conference
Year 1990

In the right situation, a speaker can use an unqual- ified indefinite description without being misun- derstood. This use of language, normal slate im- plicature, is a kind of conversational implicature, i.e. a non-truth-functional context-dependent in- ference based upon language users' awareness of principles of cooperative conversation. I present a convention for identifying normal state implica- tures which is based upon mutual beliefs of the speaker and hearer about certain properties of the speaker's plan. A key property is the precondition that an entity playing a role in the plan must be in a normal state with respect to the plan.
