By analyzing the semantic features of multi-language place names such as word formation feature, affiliation, spatial position and the like, it is found that the features of a place name such as a category, a character string and a spatial 5 position can be easily acquired and can effectively differentiate place names. Therefore, the present invention respectively constructs a place name category similarity model, a place name character string similarity model and a place name space proximity model according to the three semantic features of places. Then, by comprehensively considering a place name category similarity, a character string similarity and space proximity, the present invention provides a multi-language 0 oriented general method for calculating a place name semanteme similarity. Compared with a place name similarity calculation method which only considering a place name character string or a spatial geometric feature, the method provided by the present invention can remarkably improve the calculation accuracy of the place name similarity, and can still better satisfy the application requirements for multi-language place name query, matching and share services in the big data 5 environment. 0
