[Objective] This paper researches on the acquisition of synonym from patent query logs. [Methods] Propose a method based on the analysis of user behavior. Use logic expression parser to generate candidate synonym pairs, combine features such as pinyin, Chinese character pattern, abbreviation, traditional Chinese and simplified style to generate a synonym dictionary. [Results] Experiment results show that precision rate reaches 74.5%. This method generates 17 495 synonym pairs and the scale of dictionary exceeds some existing methods. [Limitations] This method is feasible for library and information retrieval with complex expressions. [Conclusions] This research provides a certain significant reference for log-based knowledge acquisition.
