Most commercial search engines give the same results for the same query, not considering the user's interest. User profiling is a fundamental component of any personalization application. Most existing user profiling strategies are based on object that users are interested in ( positive preferences), but not the objects that users dislike ( negative preferences). This paper focuses on search engine personalization and develop several concept-based user profiling methods that are based on both positive and negative preferences
