1.2.1 Introduction of the Speaking Elevator Sytem

The Saarbrücken computational linguistics department has a speaking elevator.

The Saarbrücken computational linguistics department's speaking elevator is the standard elevator in building 17.2. Should you ever come to Saarbrücken, it is a must to have a ride with it. Try to imagine what kind of thing you would expect it to do and see if you can get it to do it. For example, change your mind about the floor you have asked it to take you to and request another floor at different points in the dialogue.

Since we don't have the elevator here, here's an example of the kind of dialogue it handles (of course the original Saarbrücken elevator speaks German):

User:	Elevator.
System:	Which floor do you want?
User:	Professor Bill Barry.
System:	I'm taking you to the Fifth floor.
User:	Thank you.
	(Mechanical command execution follows).

The following examples depict dialogue behaviour of the kind that we would like the elevator to simulate. Below each example you find a link to a paragraph that discusses whether the speaking elevator at present displays the described behaviour, and if not how complicated it would be to extend its dialogue module (which we will elaborate in Section 2.3.1) accordingly.
