Dialogue Systems

A dialogue system (also dialog system, conversation system) is an interactive computational system designed to provide conversation-like exchanges with human users, typically by natural language. A dialogue system may be stand-alone, such as a *chatterbot, or a component of a larger system, such as the mechanism for talking with non-player characters (*NPCs) in a computer game. The wide spectrum of dialogue systems can be loosely divided into tool-like and anthropomorphic, based on whether the system’s interaction model is framed as a generic information provider, or a specific character (Jens Edlund 2008). Dialogue systems also vary significantly in terms of their algorithmic complexity: some simpler systems are designed for constrained scenarios with limited variability, whereas others use *artificial intelligence (AI) techniques to handle complex situations and increase user agency.
