From event perception and action to information states and information exchange
Robin Cooper · 2023
Abstract This chapter introduces some basic notions of a theory of action based on TTR and applies TTR to basic notions of information update in dialogue. Here we build on seminal work on the KoS framework by Jonathan Ginzburg and also related computational implementation by Staffan Larsson leading to the information state update approach to dialogue systems. These ideas have been adapted in a way that allows us to pursue the questions of grammar and semantics in the remainder of the book. A central notion is that of the dialogue gameboard which we construe as a type of information state representing the current state of play in the dialogue from the perspective of a dialogue participant. It includes the dialogue participant’s view of what has been committed to as being true in the dialogue so far and what questions are currently under discussion.
