Embodiment 1
[0110] In Embodiment 1 of the present invention, in the scenario where the basic field includes a name field, the detailed processing flow of the POI data error type positioning method is as follows: figure 2 shown, including the following steps:
[0111] Step 201: perform word segmentation processing on the name field of the POI data pair, and obtain the number of layers where each word segmentation forming the name field is located;
[0112] Specifically, according to the hierarchical parameters of the set POI name field, the word segmentation process is performed on the name field of the POI data pair, and the number of layers where each word segmentation of the name field forming the POI data pair is obtained; the POI data pair includes user The input POI data and POI raw data corresponding to the POI data input by the user.
[0113] Here, the hierarchical parameters of the POI name field can be set according to the electronic map industry classification standards and ac...
Embodiment 2
[0139] In Embodiment 2 of the present invention, in the scenario where the basic field includes an address field, the detailed processing flow of the POI data error type positioning method is as follows: image 3 shown, including the following steps:
[0140] Step 301: Carry out word segmentation processing to the address field of the POI data pair, and obtain the number of layers where each word segmentation of the address field forming the POI data pair is located;
[0141] Specifically, according to the hierarchical parameters of the set POI address field, word segmentation is performed on the address field of the POI data pair, and the layer number of each word segmentation of the address field forming the POI data pair is obtained; the POI data pair includes user The input POI data and POI raw data corresponding to the POI data input by the user.
