s301, performing space region matching operation according to the address code corresponding to the address text and the pre-established space index, and obtaining a space region matched with the address text.
In an embodiment of the application, each spatial region is defined by at least two different address encodings in the spatial index. Specifically, the address code may be geographic coordinates, such as longitude and latitude, and the like. When the address type is identified according to the address text, a space region matched with the address text is searched in a pre-established space index according to the address code corresponding to the address text. In the embodiment of the application, the space region covering the address code corresponding to the address text can be determined as the space region matched with the address text.
S302, determining the address type of the address text according to the address type of the space region matched with the address text.
In the embodiment of the application, after a space region matched with the address text is obtained according to the address code corresponding to the address text, the address type of the address text is determined according to the address type of the space region.
