Henk Zeevat (2003) The Syntax Semantics Interface of Speech Act Markers. In Proceedings Diabruck, 7th Workshop on the Semantics and the Pragmatics of Dialogue, Wallerfangen.
The paper proposes a semantics for speech acts as a generalisation of update semantics and an account of the meaning of speech act markers where they are default resetting devices. The speech act marker works on specific parameters of a given speech act and defines new valus for them.
