Abstract: A query weighted-based method is proposed for user modeling by simulating the interaction between user and search engine. First, the query log is divided into sessions according to the session division principle. Then, for each session, a group of user behavior information, such as query frequency, duration and the ranks of the clicked URLs, are employed to calculate the weight of queries. Finally, the voting method is used to generate user model. The experiment results show the effectiveness of the method over the AOL query log dataset.
