Embodiment Construction

[0038] The specific implementation manners of the group user mining method and device provided by the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] A method for mining group users provided by an embodiment of the present invention, such as figure 1 As shown, specifically, the following steps may be included:

[0040] S101. According to the historical trajectory data of multiple users composed of trajectory points, the trajectory points of each user that meet the preset time threshold, distance threshold and direction change threshold conditions constitute the daily stay points of each user, and each user The daily stay points are arranged in chronological order to form the daily stay point sequence of each user;

[0041] S102, according to each user's daily stay point sequence, count the most frequent travel start time period trajectory characteristic attributes and the most frequent end travel t...

Abstract

The invention discloses a group user mining method and apparatus. The method comprises the steps of forming daily stay points of users by daily track points, meeting preset time threshold, distance threshold and direction change threshold conditions, of the users according to historical track data, consisting of the track points, of the users, and classifying the daily stay points of the users into multiple public stay regions with semantic information; based on the stay points meeting the preset time threshold, distance threshold and direction change threshold conditions and the public stay regions with the semantic information, performing statistics on most frequent travel starting time period track feature attributes, most frequent travel ending time period track feature attributes, most frequent stay region list track feature attributes and most frequent repeated track mode track feature attributes of the users; and clustering the four track feature attributes of the users into multiple group users by adopting a preset clustering method. Therefore, the group users can be mined more comprehensively based on the historical track data.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to a mining method and device for group users. Background technique [0002] The rapid development of mobile smart devices and the mobile Internet makes it more and more convenient to obtain user location information. At the same time, the development of smart cars makes the car not only a means of transportation, but also a node of the Internet and an important source of historical trajectory data. [0003] Since the in-depth mining of historical trajectory data will generate a lot of valuable knowledge, which will lead to new business applications and business values, such as: traffic flow management, route planning based on schedule reminders, friend discovery, personalized advertising promotion services, etc. Therefore, the mining of historical trajectory data has received more and more attention. In the prior art, the mining work based on historical trajectory data that h...
