Embodiment Construction

[0024] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Before introducing the embodiments of the present invention, at first the determination method of existing resident address is introduced: DBSCAN (Chinese: based on density clustering with noise, English: Density-Based Spatial Clustering of Application with Noise) algorithm is the present There is a resident clustering algorithm, the core of which is to start from a selected core point and continuously expand to the reachable area of ​​the target, so as to obtain a maximized area including core points and boundary points. In this area, any The density between two points is connected, because the use of the DBSCAN algorithm requires the calculation of the distance between latitude and longitude, for...

Abstract

The embodiment of the present application provides a method and device for determining a resident address. The method includes: according to the collected user address information, using a preset density clustering algorithm to generate multiple address clusters corresponding to each user ID. Class cell, the user address information includes multiple latitude and longitude address information under each user ID; according to the preset sorting strategy, determine the preferred address cluster cell corresponding to each user ID, the preferred address cluster cell is multiple addresses Any cell in the clustering cell; according to the preferred address clustering cell, use GeoHash calculation to filter out the resident address information corresponding to each user ID. Therefore, GeoHash can be used to process the user's latitude and longitude data, and the preset aggregation strategy can be used to reduce the calculation time while ensuring the accuracy of data calculation. In addition, the GeoHash calculation is used to match the resident address information with the actual geographical area to improve the coverage of address information.

Description

technical field [0001] The present application relates to the technical field of information processing, in particular to a method and device for determining a resident address. Background technique [0002] In the prior art, most Internet companies collect the latitude and longitude where the user of the application uses the application every time through the SDK (Chinese: Software Tool Development Kit, English: Software Development Kit) in the application, so as to obtain each The resident address information of a user. However, this collection method is limited by whether the user is authorized and whether the user frequently uses the application. That is to say, the user's habit of using the application and the number of corresponding SDKs in the application determine the latitude and longitude that can be collected. Therefore, usually a longitude and latitude can only be collected at intervals and a certain distance, and the total number of people corresponding to the ...
