Abstract

The invention discloses a method of spatiotemporal-frequent-region mining based on multi-dimensional time granularities. The method includes: collecting location information of a moving object and corresponding time information; dividing a time period of interest according to a time granularity hierarchy to form the multi-layer time granularities; acquiring spatiotemporal staying regions of the moving object under all the time granularities according to the location information; calculating spatiotemporal frequent regions of the moving object under all the time granularities according to the acquired spatiotemporal staying regions; calculating core spatiotemporal-frequent-regions of the moving object under all the time granularities according to the spatiotemporal frequent regions; and acquiring activity rules of the moving object according to information of the core spatiotemporal-frequent-regions, and formulating an advertising strategy based on the location information. The method is used for solving the problem of spatiotemporal-frequent-region moving-object activity-law semantic-information mining insufficiency under single time granularities and scenes of location-based advertising, and improves advertising efficiency.

Description

technical field [0001] The invention relates to a method for mining frequent space-time regions, in particular to a method for mining frequent space-time regions based on multi-dimensional time granularity. Background technique [0002] With the development of mobile communication and positioning technology, a large amount of trajectory data is collected from various mobile devices, and the analysis and mining research based on trajectory data has attracted the attention of domain experts and the industry. Trajectory data records the activity rules of mobile objects in the real world. By analyzing the historical trajectories of mobile objects, the geographical areas frequently visited by mobile objects are found, and valuable information is provided for location-based services, such as traffic flow control and location-based travel recommendations. , Advertisement recommendations, location selection for shared bicycles, etc. [0003] The current research studies from the as...
