Abstract

Product suggestions provided by e-commerce recommender systems are very useful when users are overwhelmed by options to consider. Although there exist some successful zeb-based recommender systems, only a few have been designed for mobile users. In this paper, we focus on the problem of designing a user interface which providescritique-based recommendations to mobile users. The proposed system is a critique-based on-tour recommender system that supports travellers in the selection of their nation. The system does not require the user to formulate a complete query at the beginning, but rather collect the user's preferences through his critiques to the products recommended. A graphical user interface of the proposed system has been implemented for Java-enabled mobile phones. An experiment with real users was conducted to validate the system's usability. We present here the lesson learned from the empirical evaluation
