Embodiment 1

[0029] figure 1 A method flowchart of an address correction method provided by an embodiment of the present invention, such as figure 1 As shown, the method includes:

[0030] S101: Receive an address to be corrected.

[0031] For example, the received address to be corrected may be input by a user.

[0032] S102: Geocoding the address to be corrected, if the geocoding fails, perform the following steps S103-S106.

[0033] For example, the geocoding (geocoding) can be understood as determining whether the address to be corrected has a corresponding geographic address, and the geographic address can include coordinate values ​​and the like. When the address to be corrected cannot be successfully geocoded, it can be understood that the address to be corrected is not exactly the same as a known POI (Point of Interest, point of interest) and needs to be corrected, or the address to be corrected needs to be Corrected to the known correct address. If the geocoding is successful...

Embodiment 2

[0060] figure 2 A structural diagram of an address correction device provided in an embodiment of the present invention, including:

[0061] The receiving unit 201 is configured to receive the address to be corrected.

[0062] The coding unit 202 is configured to geocode the address to be corrected, and if the geocoding fails, trigger the first word segmentation unit 203:

[0063] The first word segmentation unit 203 is configured to perform word segmentation on the address to be corrected to obtain address fragments forming the address to be corrected.

[0064] The matching unit 204 is used to match each address segment with the POI in the preset point of interest POI database; if the candidate POI corresponding to the address to be corrected can be matched, the selection unit 205 is triggered;

[0065] The selection unit 205 is configured to select a candidate POI whose frequency is greater than or equal to a preset frequency threshold from the candidate POIs.

Abstract

An embodiment of the invention discloses an address correction method and device. A to-be-corrected address is received, geocoding is performed, and if geocoding fails, the following steps are performed: word segmentation is performed on the to-be-corrected address, and address fragments are obtained; the address fragments are matched with POIs (points of internet) in a POI database; if the matching succeeds, candidate POIs with the frequency larger than or equal to a preset frequency threshold value are obtained; a target POI is determined from the selected candidate POIs according to road information of the to-be-corrected address, the frequency of the selected candidate POIs and position information of the candidate POIs; the to-be-corrected address is corrected according to the target POI. Thus, the POIs in the POI database are all obtained through collection in field in advance, the candidate POIs with higher frequency are more common POIs, therefore, the accuracy of correction of the to-be-corrected address according to the determined target POI is higher, and the accuracy of correction to the to-be-corrected address is improved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to an address correction method and device. Background technique [0002] At present, online shopping has become one of the main ways for people to purchase goods. When purchasing goods, users can directly place an order after filling in the waybill information (including the waybill address). However, since the user fills in the waybill address by himself, there are often filling errors, such as typos in the address, more or less words in the address, homophonic typos, etc. If these waybill addresses are not corrected, the waybill address may appear when placing an order Error, item could not be delivered accurately. [0003] How to correct the waybill address filled in by the user before the user places an order has become a technical problem to be solved urgently. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a...
