RE: [PHP] Anyone worked on Question Answering system?

Thanks for your idea... I do believe that a "most clicked" table should exist in my DB... In fact, How do i make chocoalte cake, would be reduced to make chocolate cake... What i meant in my original e-mail was that it would know that MAKE CHOCOLATE would refer to a recipe, and that the specific recipe would be for CHOCOLATE CAKE. So basically it would know that all RECIPE questions begin with : "Where can i find a recipe for: (Chocolate Cake/Chocolate Mousse / etc / etc)"... The idea of a most-clicked would be good, based on important words, and clicked answers... > -----Original Message----- > From: scott@globalhost.com [mailto:scott@globalhost.com] > Sent: Sunday, October 29, 2000 4:08 AM > To: Roy Nasser > Subject: RE: [PHP] Anyone worked on Question Answering system? > > > How would your system respond to \"How can I make a picture > of a chocolate cake?\" or \"Can a chocolate cake make me sick?\" > > autonomy.com has a very advanced system for relating > questions to information stored in a database. > > A simpler system might involve > 1.
