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 invention provides a resident address determination method and device, and the method comprises the steps: generating a plurality of address clustering cells corresponding to each user ID through employing a preset density clustering algorithm according to collected user address information, and enabling the user address information to comprise a plurality of longitude and latitude address information under each user ID; Determining a preferred address clustering cell corresponding to each user ID according to a preset sorting strategy, the preferred address clustering cell being any one of a plurality of address clustering cells; And according to the preferred address clustering cell, utilizing GeoHash calculation to correspondingly screen out resident address information corresponding to each user ID. Therefore, the GeoHash can be used for processing the latitude and longitude data of the user, and the calculation time is shortened while the accuracy of data calculation is ensured by utilizing a preset aggregation strategy. In addition, the resident address information is made to correspond to the actual geographic area through GeoHash calculation, and the coverage rate of the address information is increased.

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 ...
