Method and device for identifying linkage type POI (Point Of Interest) data

The invention discloses a method and a device for identifying linkage type POI (Point Of Interest) data. The method for identifying the linkage type POI data comprises the steps of obtaining a to-be-identified POI data set; cutting a name text of POI in the to-be-identified POI data set, and obtaining the first i cutting fragments Ti of the name text, wherein i = 1, 2, 3 ellipsis; calculating the occurrence number C (Ti) of the name text of each Ti within the range of the to-be-identified POI data set according to the text content of the cutting fragments; and searching Ti which enables [C (Ti)-C (Ti+1)] to be larger than a preset threshold value in a calculating result, and identifying multiple POI data corresponding to C (Ti) into POI data which are in mutual linkage. By adopting the technical scheme, POI data with a linkage relation can be automatically identified from large-capacity POI data.
