Conversational AI 5-MODELING CONVERSATION IN DIALOGUE SYSTEMS
Conversational interactions in current systems fall into three distinct types in terms of the types of interaction they support and which participant initiates and controls the dialogue.
1. User-initiated dialogues: Interactions initiated by the user are typical of the way users interact with smart speakers and virtual assistants. The interaction is usually brief, consisting of a two-turn exchange in which the user asks a question or issues a command and the system responds.
2. System-directed dialogues: In these interactions the system controls the dialogue. The system asks series of questions and helps user to complete the task (e.g. To book a reservation in hotel)
3. Multi-turn open-domain dialogues: These are extended interactions in which both the system and the user take turns as in natural conversations between humans, where the conversation extends over potentially many turns and can involve a range of topics. Turn by turn they have the natural conversation.
