摘要：

Query auto-completion of search engines provides good experience for the users. With the user's search intention changing over time, time-sensitive query auto-completion (TSQC) comes to be a research focus. Different from traditional query auto-completion, recommendation list of TSQC is made according to the attaching time features of the query words. First, the definition and classification of TSQC are introduced. Then the key steps of TSQC are presented and analyzed, which include type judgment of time-sensitive query, weight calculation of candidates and recommendation list ranking. Finally, technique evaluation and future development of TSQC are analyzed and summarized. ©, 2015, Chinese Institute of Electronics. All right reserved.
