Re: Just a quick question.
At Xerox there was a natural language understanding project. They built a small database of airline schedules and let people try it out:
"Book me a flight from San Diego to San Francisco."
"I have a flight leaving at 12:00."
"I'd like one a little closer to 6:00."
"I have one at 12:01"
[There was a flight at 6:00 but the customer specified "a little closer." He meant a lot closer.]
