“we envision a computer interface that utilizes a thesaurus, spelling correction, displays  of what is possible, and knowledge of the user and the task to take part in a negotiation of the user’s command. We could imagine, for example, a dialog in which the user makes a free-form request, the computer responds with a list of possible tasks that seem to match the request, and both engage in a dialog to focus on the request the user actually intended.”

Sounds interesting
