It is very difficult, so before the address matching, these interferences can be removed first, that is, the address information is preprocessed in a format. For example, as shown in Table 1 below, there are several types of preprocessing listed.
- the address feature information herein may include one or more of latitude and longitude information, POI information of interest points, and digital substring information (such as road number, building number, floor, and room number, etc., which are regarded as digital substring information).
- Each of the first address information or the second address information may have one or more digital substrings, each of the digital substrings corresponding to a range of addresses of the address, and different digital substrings of the same address correspond to different ranges of addresses, such as roads.
- the number and building number correspond to different location ranges.
- the latitude and longitude information corresponding to the first address information and the second address information may be found by querying a latitude and longitude library storing the mapping relationship between the address information and the latitude and longitude.
- the POI information may be extracted according to the keyword information of the preset corresponding POI information (for example, based on the keyword “road”: No. 256 Tianmushan Road, No. 18 Wantang Road), from the first address information and the second address information. Extract POI information.
- the digital substring information is extracted according to a preset digital substring matching mode (for example, matching an exit number, a building number, a floor, and a room number in sequence).
- the first address information is “2nd Floor, MM Building, No. 256 Tianmushan Road, Hangzhou, Zhejiang province”
- the second address information is “2nd Floor, MM Building, No. 18 Wantang Road, Hangzhou, Zhejiang province”; for example, the first address information is analyzed.
- the POI information is 256 Tianmushan Road, the latitude and longitude is (30.122, 102.589), and the fuzzy matching is used to extract the road number: 256, building number: no, floor: 2nd floor, room number: none, the number of the first address information
- the substring information is: 256*2*, where "*" indicates that the location range of the identifier does not have a corresponding digital substring; the second address information is parsed, and the POI information is obtained as No. 18 Wantang Road, with a latitude and longitude of 30.121, 102.583), using fuzzy matching to extract the way number: 18 No., No.: No, Floor: 2nd floor, Room No.: None, the digital substring information of the second address information is 256*2*.
- the first address information may be searched for and matched with the first address information according to a preset address feature matching condition.

Since the embodiment of the present application needs to perform searching based on the latitude and longitude points, a 2-dimensional k-d tree (ie, a 2-d tree) can be used. As shown in FIG. 3, it is a latitude and longitude scatter plot, and each dot represents a latitude and longitude point corresponding to an address information. If the traversal method is used, the distance between the latitude and longitude corresponding to each extracted second address information and the latitude and longitude corresponding to the first address information to be matched is calculated in turn, which wastes a lot of computing resources, and uses a 2-d tree search method. It is possible to select only the latitude and longitude (corresponding to the point in the dotted line frame) of the second address information whose latitude and longitude distance is relatively close to the first address information, so that a large amount of computing resources can be saved.
- the POI information may be extracted from the first address information and the second address information respectively. If the separately extracted POI information is the same, the POI corresponding to the second address information and the first address information respectively is considered. The information is the same; however, since the same address usually has multiple different description modes, when the two account systems describe the same address in different description manners, the first address information and the second address information corresponding to the same address are extracted. The POI information may be different.
