Abstract

The invention provides a method and an apparatus for obtaining key position data of a user, relates to the technical field of information, and solves the problem of relatively low precision of obtaining the key position data of the user at present. According to the main technical scheme, the method comprises the steps of firstly obtaining Kth nearest neighbor position points corresponding to position points of the user respectively from the position points of the user, and obtaining distances between the position points and the corresponding Kth nearest neighbor position points; secondly, extracting threshold position points from the position points according to the distances between the position points and the corresponding Kth nearest neighbor position points; and finally, taking Kth nearest neighbor distances and K values corresponding to the threshold position points as inputs of a DBSCAN algorithm, and performing clustering on user position data to obtain the key position data of the user. The method and the apparatus are mainly used for obtaining the key position data of the user.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method and device for acquiring user key position data. Background technique [0002] With the popularization of mobile Internet services, more and more user location data are collected and stored, and various offline application services rely more and more on user location data. Among user location data, key location data such as the user's work and home locations are widely used in many offline application services, such as the recommendation of commuting routes in map application services. [0003] At present, when acquiring user key location data, it is usually extracted from the user location data based on DBSCAN (Density-Based Spatial Clustering of Applications with Noise, a density-based clustering algorithm). However, because the input parameters of the existing DBSCAN algorithm are manually input, for massive user location data, the input parameters of th...
