The results suggest that choice among simple categories constitutes the most effective means of capturing user preferences and that standard tours would not adequately represent the wide array of interest profiles identified.
Abstract
Knowing tourists' individual preferences provides the possibility to offer personalised tours. The challenge is to capture these preferences using a mobile device. During a field study in Görlitz three methods for preference elicitation were evaluated. The results served to clarify fundamental questions en route to developing a personal tour guide: 1) Is it possible to seed interest profiles in the mobile context with all its distractions that allow the accurate prediction of rankings of concrete sights? and, 2) Are the interest profiles sufficiently diverse to justify the computation of personalized tours instead of selecting from a list of standard tours'? The results suggest that choice among simple categories constitutes the most effective means of capturing user preferences and that standard tours would not adequately represent the wide array of interest profiles identified.
