Title:
INFORMATION PUSHING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/258905
Kind Code:
A1
Abstract:
An information pushing method and device. The method comprises: a server obtains and records a coordinate point of the location of a user terminal reported by the user terminal, and a moment when the location information is reported (101); determine the coordinate point, which satisfies a preset condition, of each user in a first preset time (102); divide the minimum rectangular area containing all the coordinate points which satisfy the preset condition into grids taking a preset step size as the unit, and establish a mapping relationship between the coordinate point in each grid and the corresponding grid (103); in a clustering process by a grid search-based DBSCAN algorithm, search for corresponding neighborhoods by means of an eight-direction neighborhood mode by taking the grid having a mapping relationship with the coordinate point as the unit (104); map grids in each cluster after clustering into the coordinate points in the corresponding grids according to the mapping relationships (105); for any cluster, push information at the corresponding locations according to the portraits of the users corresponding to the coordinate points in the cluster (106). The method can improve the information pushing efficiency.
