Attackers may attack based on the semantic of the user\u2019s location and user\u2019s query location. A few of existing works on location privacy protection consider to protect the user\u2019s location and his query location simultaneously, while the query location may reflect his requirement. In this paper, based on the existing location privacy protection framework, we first generate sensitive weight documents based on the user\u2019s sensitivity to different location semantics automatically, then obtain the best collaborative segment for <jats:italic>k<\/jats:italic>-anonymity of the user\u2019s location by using the reinforcement learning algorithm, and finally, the bidirectional <jats:italic>k<\/jats:italic>-disturbance of the user\u2019s location and query location is performed based on the location semantics in real road network environment.
