A human Dialogue is a human to human interaction.
turn each contributino to a conversation is called a &ldquo;turn&rdquo;, which contains a sentence, multiple sentences, or a single word
turn-taking when to take the floor who takes the floor what happens during interruptions? barge-in barge-in is the property to allow the user to interrupt the system
end-pointing deciding when a human has stopped talking, compute, etc.
speech-act each turn is actually an &ldquo;action&rdquo; performed by the user
constatives: committing the speaker to something being the case (answering, denying) directives: ask the addressee to do something (advising, ordering) com missives: commuting the speaker to future action (planning, voving) acknowledgement: reflecting the speaker&rsquo;s attitude for something (apologizing, greeting, etc.) common ground grounding is the problem of acknowledging and reflecting the state of interaction; such as the elevator lighting up when pressed.
acknowledgements and repeats is a way of grounding.
we need to make sure that the system acknowledges user interaction
adjacency pairs question =&gt; answer proposal =&gt; acceptance/rejection complements =&gt; downplay two-pair composition maybe interrupted or separated by a sub-dialogue
conversational initiative Sometimes, such as during interviews, only one agent has initiative. This is not true most of the time during human-human interactions.
mixed initiative is hard to achieve, usually we make dialogue systems as passive environments&mdash;only user and system understanding.
