Our student team Chan Wai Man (Witman), Fong Kin Fong (Peter), and Wong Kai Hong (Nick), supervised by Dr. Robert P. Biuk-Aghai from the Department of Computer and Information Science of the Faculty of Science and Technology attended the Macau Computer Association (MCA) Annual Dinner on 15 January 2009. It was also celebrating 25 years its establishment. The dinner included a prize giving ceremony of MICTA (Macau Information Communication Technology Awards) which our student group won the silver award (i.e. 2nd prize) for their project Macau Tourism Recommender System.

This project has developed a recommender system which is an extension of the MacauMap system. It provides a suggested travel itinerary to a tourist based on input about the tourist’s preferences, official rating of each tourist spot, and all user feedback for each spot. Tourists use their mobile device such as mobile phone or PDA to indicate their preferences for different types of tourist spots (temples, churches, museums, entertainment, nature, etc.), as well as their desired begin and end time and place. These requirements are transmitted as a call to a web service on a recommendation server which generates a suitable travel itinerary. A genetic algorithm is used for determining the itinerary. Then a fuzzy logic module calculates the suitable stay time for each spot based on the user’s preferences. A schedule is completed for the itinerary including travel times by bus or on foot which are calculated for each pair of spots in the itinerary. The itinerary is sent back to the mobile device. The tourist may also modify an itinerary by reordering spots or removing spots, which recalculates schedule and travel times and is performed locally on the device without requiring another server access.
