Abstract

Embodiments of the present invention provide a trajectory data labeling method and device. The method includes: obtaining user feature description information and first information point POI track information corresponding to the user feature description information through public data sources; according to the first POI The track information acquires the first POI type track data; the first POI type track data is clustered according to the preset time period, and the user characteristic description information corresponding to different time periods is obtained; according to the first POI type track data and the pending Mark the corresponding relationship of the POI type track data and the time information corresponding to the POI type track data to be marked, and mark the user feature description for the user corresponding to the POI type track data to be marked. In the embodiment of the present invention, the automatic labeling of user feature description is realized, and the accuracy and efficiency of labeling are improved.

Description

technical field [0001] The invention relates to communication technology, in particular to a track data labeling method and device. Background technique [0002] With the explosive growth of mobile networks and the wide application of mobile smart devices, mobile user trajectory data has become an important source of big data, where user trajectory data is also called user spatiotemporal distribution data. When the user equipment (User Equipment, UE for short) used by the user is on the Global Position System (Global Position System, GPS for short), the information about the movement of the UE in time and space is the trajectory data of the user using the UE. When a user uses a mobile network through a UE, the Mobile Broadband (MBB) data recorded by the base station also contains a large amount of track data of the user. The statistics and in-depth mining of these trajectory data have brought new commercial applications, such as: store location selection, service recommenda...
