Most simply look for verb and objects and then ignore everything else. The effect is sentences like this: "Today I think that I would like to take that box and put it on that shelf." Are exactly the same as "sentences" like this: "box put (on) shelf" Think about it, when NLI was all the craze (for games like Zork), these programs were less than 256 kb. They couldn't be very complex, but they sure *SEEMED* to understand what you typed. It largely is a trick, but it works. Do you think there is some way that Narval and Piper could share an NLI "engine"? Jeff -- J.W.
