Conversational scoreboard

In linguistics and philosophy of language, the conversational scoreboard (or conversational score) is a theoretical representation of the state of a conversation at a given moment. It treats discourse as a kind of game in which each speech act updates a structured collection of contextual parameters – for example the common ground, the questions currently under discussion and the interlocutors' public commitments – thereby constraining which subsequent moves are appropriate or felicitous.
