Embodiment 1

[0084] image 3 A flow chart of an address selection method provided by an embodiment of the present invention can be obtained by figure 2The addressing device 10 shown performs as image 3 As shown, the address selection method may include the following steps:

[0085] S101: Obtain a movement point set of each user among M users, each user's movement point set includes n movement points, M is an integer greater than or equal to 1, and n is an integer greater than or equal to 2.

[0086] Wherein, each moving point may correspond to a piece of location data, such as location data in the form of , etc.

[0087] It should be noted that, in the embodiment of the present invention, the number of motion points corresponding to each user may be the same or different, and most of the M users are in the state of motion, and the motion points of these users There are multiple users. Of course, the M users do not exclude users in a static state that only contain a single movement poi...

Embodiment 2

[0180] Figure 6 A structural diagram of an addressing device 20 provided for an embodiment of the present invention, as shown in Figure 6 As shown, the device 20 may include:

[0181] The acquisition unit 201 is configured to acquire a movement point set of each user among M users, the movement point set of each user includes n movement points, the M is an integer greater than or equal to 1, and the n is greater than or equal to or an integer equal to 2.

[0182] The determination unit 202 is configured to select a target address from the candidate address set according to the movement point set of each user acquired by the acquisition unit 201; the target address is the candidate address with the largest number of affected users, and the The candidate address set includes at least two candidate addresses, and the users affected by the candidate addresses are: users whose probability of being affected by the candidate addresses is greater than or equal to a preset threshol...

Abstract

The invention relates to the field of data mining technology, and specifically, to a method and device for selecting a location. The invention resolves a problem in which a location selected by a PRNN scheme, given that all people remain stationary at locations, is not accurate enough. In one embodiment, the method comprises: acquiring a plurality of moving points of each of M users; and selecting, according the plurality of moving points of each of the users, and from a candidate location set, a target location, wherein the target address is the candidate address affecting most of the users.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to a site selection method and device. Background technique [0002] The problem of location selection, especially the location selection problem based on the greatest influence, is a hotspot in the field of spatial data research. Its core is to select the optimal location from many candidate locations, so that the facilities deployed at this location can affect the most target population. . [0003] At present, to establish a new facility so that it can be accessed and used by more people, there are usually many candidate locations. At this time, people can use the following maximum probability reverse nearest neighbor (Probabilistic ReversedNearest Neighbor, PRNN) technology Select the optimal address from many candidate addresses: Assuming that the crowd remains static (that is, people are located at a certain point), the candidate address closest to more people is determine...
