For example, a first can be termed a second and, similarly, a second can be termed a first without departing from the scope of one or more embodiments of the present description. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
First, the noun terms to which one or more embodiments of the present specification relate are explained.
The Geohash is used for converting the longitude and latitude of two dimensions into character strings, and each character string represents a certain rectangular area. That is, all points (latitude and longitude coordinates) in the rectangular area share the same Geohash character string, and the longer the character string, the more precise the range is represented.
A POI (Point of Interest), in a geographic information system, a POI may be a house, a shop, a mailbox, a bus station, etc.
In the present specification, a method for matching a POI with a merchant and a method for authenticating the POI are provided, and the present specification relates to an apparatus for matching a POI with a merchant, an apparatus for authenticating the POI, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments one by one.
Fig. 1 shows a flowchart of a method for matching POIs according to an embodiment of the present specification, including steps 102 to 108.
Step 102: and acquiring the transaction positioning data of the merchant.
For example, the transaction location data (LBS, location based service) of the merchant terminal may be obtained through a radio communication network of a telecommunication mobile operator, such as a GSM network and a CDMA network, or an external location means, such as GPS, under the support of a geographic information system platform, and may include location information of the buyer at the time of transaction, location information of the merchant incoming item, and the like. The geographic information system is used for storing map information, providing electronic maps and providing people to inquire target geographic information.
Step 104: and calculating the Geohash corresponding to the positioning point of the merchant by using the transaction positioning data.
There may be multiple merchant transactions for one merchant, and in this embodiment of the present specification, the location point of the merchant may be determined based on a clustering manner. The clustering method is not limited, and for example, a clustering method such as Geohash and DBSCAN can be used. The positions of the merchants are positioned in a clustering mode, so that the accuracy of merchant positioning can be improved, and the geographic error of the merchant positioning positions is reduced.
The Geohash adopts the dichotomy to continuously reduce the longitude and latitude intervals to carry out binary coding, code parity bits generated by the longitude and latitude are crossed and combined, and then the calculation is carried out in an alphanumeric expression mode, so that the calculation speed is high, and therefore, the Geohash is adopted in the embodiment of the specification to carry out clustering. Specifically, for example, the calculating, by using the transaction location data, a Geohash corresponding to the location point of the merchant may include: clustering the transaction positioning data in the preset time period of the merchant by adopting a Geohash, wherein one category corresponds to one Geohash; and selecting the Geohash with the largest transaction quantity as the Geohash corresponding to the positioning point of the merchant, and calculating the average value of the transaction positioning data in the Geohash as the positioning point of the merchant. As another example, the central point of the Geohash with the largest transaction amount may be used as the location point of the merchant.
Step 106: and acquiring the Geohash adjacent to the Geohash corresponding to the positioning point.
In this embodiment of the present specification, the reason why the Geohash adjacent to the Geohash corresponding to the location point is obtained is that there may be different geohashes for the POI points matching with the location point. For example, as shown in the map diagram of fig. 2, the shops corresponding to the two POI points near the positioning point 201 are the shop 203 and the shop 204, respectively. Wherein the Geohash code of the shop 203 is the same as the Geohash of the localization point 201, while the Geohash code of the shop 204, which is more matched to the localization point 201, is different from the localization point 201. By using the Geohash corresponding to the locating point 201 and the geohashes of the eight neighboring domains as the search range, a more matched shop 204 can be searched, and a better matching effect is achieved.
As shown in the map diagram of fig. 2, the Geohash adjacent to the Geohash corresponding to the anchor point 201 may include: and one or more of eight adjacent Geohash positioned above, below, leftward, rightward, above-left, above-right, below-left and below-right the Geohash corresponding to the positioning point. By the implementation method, eight adjacent GeoHashs of the GeoHash corresponding to the locating point can be brought into the search range, and the matching effect is improved.
The Geohash is essentially a way of filling space with a Peano curve, and according to the generation principle of the Peano curve, coordinate tables (including a longitude table and a dimension table, each including four directions) of upper, lower, left and right points of a certain character can be determined. Therefore, according to the curve generation principle, characters corresponding to the direction can be recursively calculated from the last character of the Geohash corresponding to the locating point according to the direction of the adjacent Geohash, so that the Geohash adjacent to the Geohash corresponding to the locating point is reversely deduced.
Step 108: and searching the POI points matched with the positioning points from the geographic information system by taking the Geohash corresponding to the positioning points and the Geohash adjacent to the Geohash corresponding to the positioning points as search ranges according to the Geohash corresponding to the POI points in the geographic information system.
In order to facilitate searching for a POI point matching a location point, the POI point in the geographic information system may be mapped to a corresponding Geohash in advance.
Because the acquisition of the geographic information has certain errors, the matching between the POI point and the positioning point is suitable for balancing the accuracy and the coverage rate by adopting a certain radius so as to achieve a better matching effect. For example, the Geohash corresponding to the positioning point and the Geohash adjacent to the Geohash corresponding to the positioning point may be used as a search range to search out the POI points within a preset radius range from the positioning point. And one or more POI points within a preset radius range from the positioning point can be selected. Specifically, the Geohash corresponding to the locating point and the POI points in the Geohash adjacent to the Geohash corresponding to the locating point may be extracted, and a distance between each two of the locating point of the merchant and the extracted POI points may be calculated by using a spherical distance calculation method, so as to screen out the POI points whose distance is within a preset radius range. In the embodiment, the initial search is carried out through the Geohash, the accurate search is carried out by utilizing the preset radius, the error of geographic information acquisition is effectively balanced, and a better matching effect is achieved.
Since store merchants (such as transportation merchants, mobile vendors, online transaction merchants, etc.) are suitable for matching POI points, in an embodiment of this specification, it may be further determined, according to the transaction location data of the merchant within a preset time period, whether transaction locations of the merchant within the preset time period collectively determine whether the merchant is a store merchant; and if the POI points are concentrated, the merchant is considered as a store merchant, and the POI points are continuously matched with the merchant.
The centralized judgment condition may be set according to the implementation environment, and the embodiments of the present specification are not limited. For example, in an implementation of clustering by using geohashes, the matching may be determined according to a percentage of transaction location data of a merchant aggregated in one Geohash, and if the percentage is within a preset range meeting a concentration requirement, for example, the percentage aggregated in one Geohash exceeds 80%, the geo hash is determined to be concentrated, and the step of selecting the geo hash with the largest number of transactions as the geo hash corresponding to the location point of the merchant is performed so as to continue to perform POI point matching on the merchant. As another example, the transaction location data of a merchant may be determined to be concentrated when the distance between the geohashes is shorter than a preset distance, for example, 80%, for example, the distance is within a preset concentration distance range. In the implementation of performing POI point matching on multiple merchants at a time, centralized merchants can continue to perform POI point matching, and non-centralized merchants are removed.
It can be seen that, in the method for matching a business point to a POI provided in the embodiments of the present specification, matching of POI points is performed through a Geohash of a location point and an adjacent Geohash, which can greatly reduce a search space and improve search efficiency and accuracy, so that information provided by the matching POI points can be obtained as information of the business, and a purpose of quickly and accurately obtaining information of the business is achieved.
The method for matching a merchant with a POI is further described below with reference to fig. 3, taking an application of the method for matching a merchant with a POI provided in this specification in merchant authentication as an example. Fig. 3 is a flowchart illustrating a processing procedure of a method for matching a POI with a merchant according to another embodiment of the present disclosure, where the specific steps include steps 302 to 320.
Step 302: transaction location data for a plurality of merchants is obtained.
Step 304: and for each merchant, clustering the transaction positioning data in the preset time period of the merchant by adopting a Geohash, wherein one category corresponds to one Geohash.
Step 306: and for each merchant, judging whether the transaction positions in the merchant preset time period are centralized or not according to the transaction positioning data in the merchant preset time period.
Step 308: and selecting Geohash with the largest transaction quantity as Geohash corresponding to the positioning point of the merchant according to the merchants in the transaction position set, and calculating the average value of the transaction positioning data in the Geohash as the positioning point of the merchant.
Step 310: and removing the merchant from the authentication process aiming at the merchant with the non-centralized transaction position.
Step 312: and aiming at each merchant with concentrated transaction positions, acquiring eight adjacent Geohash which are respectively positioned above, below, left, right, above left, above right, below left and below right of the Geohash corresponding to the merchant positioning point.
Step 314: and aiming at each merchant in each transaction position set, taking the Geohash corresponding to the positioning point of the merchant and eight adjacent Geohash as search ranges, and searching out POI points within a preset radius range from the positioning point.
Step 316: and comparing the business name and the contact information provided by the searched POI point with the business name and the contact information provided by the corresponding business.
Step 318: and if the merchant authentication is consistent, confirming that the merchant authentication is passed.
Step 320: after the authentication is passed, the information which is missing corresponding to the merchant is extracted from the information provided by the POI point and is supplemented to the account information of the corresponding merchant.
As can be seen, the method for matching a POI by a merchant provided in the embodiments of the present specification uses a Geohash to perform clustering, has a fast calculation speed, and can greatly reduce a search space and improve search efficiency and accuracy by matching POI points through the Geohash of a location point and an adjacent Geohash. In the application of merchant authentication, the information provided by the POI point can be used, namely, the information provided by the merchant is authenticated based on third-party data of a geographic information system, the source of the authentication information is objective and fair, and the purpose of efficient and reliable merchant authentication is realized.
Corresponding to the above method embodiment, the present specification further provides an embodiment of a device for matching a business with a POI, and fig. 4 shows a schematic structural diagram of the device for matching a business with a POI, provided by an embodiment of the present specification. As shown in fig. 4, the apparatus includes: a positioning data acquisition module 402, a positioning code calculation module 404, an adjacent code acquisition module 406, and a search matching module 408.
The location data acquisition module 402 may be configured to acquire transaction location data for a merchant.
The location code calculation module 404 may be configured to calculate a Geohash corresponding to the location point of the merchant by using the transaction location data.
The neighboring code obtaining module 406 may be configured to obtain a Geohash neighboring the Geohash corresponding to the anchor point.
The search matching module 408 may be configured to search, according to the Geohash corresponding to the POI point in the geographic information system, the POI point matched with the location point from the geographic information system by using the Geohash corresponding to the location point and the Geohash adjacent to the Geohash corresponding to the location point as a search range.
It can be seen that, in the method for matching a business point to a POI provided in the embodiments of the present specification, matching of POI points is performed through a Geohash of a location point and an adjacent Geohash, which can greatly reduce a search space and improve search efficiency and accuracy, so that information provided by the matching POI points can be obtained as information of the business, and a purpose of quickly and accurately obtaining information of the business is achieved.
The Geohash adopts the dichotomy to continuously reduce the longitude and latitude intervals to carry out binary coding, code parity bits generated by the longitude and latitude are crossed and combined, and then the calculation is carried out in an alphanumeric expression mode, so that the calculation speed is high, and therefore, the Geohash is adopted in the embodiment of the specification to carry out clustering. For example, fig. 5 shows a schematic structural diagram of an apparatus for matching POIs for a merchant according to another embodiment of the present specification. As shown in fig. 5, the positioning code calculating module 404 may include: the clustering submodule 4041 is configured to cluster the transaction location data in the preset time period of the merchant by using a Geohash, and one class corresponds to one Geohash. The mean value calculating sub-module 4042 is configured to select the Geohash with the largest transaction number as the Geohash corresponding to the location point of the merchant, and calculate an average value of the transaction location data therein as the location point of the merchant.
Because the acquisition of the geographic information has certain errors, the matching between the POI point and the positioning point is suitable for balancing the accuracy and the coverage rate by adopting a certain radius so as to achieve a better matching effect. Therefore, in an embodiment of the present specification, the search matching module 408 may be configured to search out, according to the Geohash corresponding to the POI point in the geographic information system, a POI point within a preset radius range from the location point by using the Geohash corresponding to the location point and the Geohash adjacent to the Geohash corresponding to the location point as search ranges.
The foregoing is an exemplary scheme of the device for matching POIs for a merchant according to this embodiment. It should be noted that the technical solution of the device for matching a business with a POI belongs to the same concept as the technical solution of the method for matching a business with a POI described above, and details of the technical solution of the device for matching a business with a POI, which are not described in detail, can be referred to the description of the technical solution of the method for matching a business with a POI described above.
Fig. 6 shows a flowchart of a method for merchant authentication, including steps 602 to 606, according to an embodiment of the present description.
Step 602: and acquiring information to be authenticated provided by the merchant.
For example, the merchant name and contact information submitted by the third-party platform when the merchant requests authentication may be obtained to wait for authentication information.
Step 604: the method for matching the POI of the merchant according to any embodiment of the present specification is applied to search out the POI point matched with the positioning point of the merchant.
Step 606: and authenticating the information to be authenticated provided by the merchant by using the information provided by the POI point.
For example, the business name and the contact address provided by the POI point may be compared with the business name and the contact address provided by the business, such as a phone; and if the merchant authentication is consistent, confirming that the merchant authentication is passed. By the embodiment, the merchant name and the contact information provided by the merchant can be authenticated based on the merchant name and the contact information provided by the searched POI, the authentication information source is objective and fair, and the purpose of efficient and reliable merchant authentication is realized. And under the condition that a plurality of POI points matched with the positioning point exist, the merchant name and the contact way of one POI point are consistent with the merchant name and the contact way provided by the merchant, and the merchant can be considered to pass the authentication.
