[Objective] This paper tries to discover the important locations of users, aiming to provide good data support for user behavior studies. [Methods] We presented a model for predicting important locations based on user representation. First, we proposed a vectorized representation method to predict user behaviors based on Word2Vec. Then, we constructed a user relationship network based on the similarity of user vectors to extract core users. Finally, we predicted the important locations by the behaviors of core users. [Results] The precison of important locations classifiction was 7% higher than those of the exisitng methods. Moreover, the residential and commercial areas were shown in the labeled map. [Limitations] Our method can only identify residential and business areas. [Conclusions] The proposed method could effectively find important locations and provide more supports to study user behaviors.
