The development of location-based services (LBS) caused serious privacy concerns.Semantic-based pri-vacy-preserving approaches is an important part of privacy protection in LBS.The recent work on location privacy protection based on semantics were summarized,including key factors in design of privacy protection,the feasibility of semantic protection,related concepts.Then semantic-based location privacy-preserving mechanisms,measure-ment methods of semantic similarity,evaluation index of privacy for semantic location privacy were discussed.Fi-nally,some future research directions of semantic-based location privacy protection were prospected.
