The following Restaurant Selection system is a small demonstration that displays some of Exsys CORVID's features. CORVID expert systems can advise among a group of possible competing alternatives even if the user's requests may not exactly match any of the possible options. In this case, the system advises on where to go to dinner based on occasion, atmosphere, and food preferences.
The CORVID system interacts with you by asking initial questions to obtain data on your preferences. More focused queries are then made by the system based on information you have already provided. Unnecessary questions are not asked, but when your answer indicates more details are needed in a specific area, the system asks follow-up questions. Recommended restaurants are presented, along with specific comments on potential disadvantages the restaurant might present for the occasion (e.g. too noisy, not private, etc.)
