III. PROBLEM SOLUTION Based on the above-mentioned reasons, we propose an expert system for a hotel booking system. The main idea of the proposed expert system is to interconnect the hotel with places, activities and interesting events around, and based on user preferences to suggest suitable hotel services and suitable activities for the hotel guest. The proposed expert system will be connected to a simple questionnaire to detect guest preferences [12]. The expert system consists of a knowledge base which contains IF-THEN rules for determining which hotel services and activities around the hotel are more or less suitable for the hotel guest.
