Problems solved by technology

In the prior art, the acquisition methods of the accompanying relationship include: first, analyzing the spatio-temporal correlation of the actual travel trajectory data of the individual to obtain the accompanying relationship between individuals. This method not only has a large amount of calculation, but also obtains The data of accompanying relationship is sparse; the second method is to use virtual social identities to conduct association relationship analysis to obtain accompanying relationship. Since the correspondence between virtual identities and real individuals is extremely vague, it is difficult to convert from virtual individuals to real individuals

Embodiment 1

[0049] refer to figure 1 , figure 1 It is a flow chart of a specific embodiment of a method for obtaining an accompanying relationship based on a time-space trajectory in the present invention, and a method for obtaining an accompanying relationship based on a time-space trajectory includes the following steps:

[0050] The time-space trajectory acquisition step is to obtain the time-space trajectory information of the identity feature. The identity feature is the unique coded information of the device representing an individual. The space-time trajectory information includes the location information and time information of the identity feature. Specifically, the time-space trajectory information refers to the unique coded information of the device The specific time of being collected and the specific location of the collection device that uniquely encodes the information;

[0051] The identity feature pair acquisition step is to judge the spatiotemporal similarity of any two...

Embodiment 1

[0076] Obtain embodiment 2 based on embodiment 1, a kind of accompanying relationship acquisition system based on space-time trajectory, comprising:

[0077] The spatio-temporal trajectory acquisition module is used to obtain the spatio-temporal trajectory information of the identity feature, the identity feature is the unique coded information of an individual device, and the spatio-temporal trajectory information includes the location information and time information of the identity feature;

[0078] The identity feature pair acquisition module is used to judge the spatiotemporal similarity of any two identity features according to the spatiotemporal trajectory information to obtain the identity feature pair with spatiotemporal similarity;

[0079] The identity feature pair exclusion module is used to judge whether the identity feature pair with temporal and spatial similarity corresponds to the same individual so as to obtain the identity features with temporal and spatial s...

Embodiment 3

[0083] The clustering of crowds exists in groups with virtual social relations, but also in groups with strong spatio-temporal associations. Therefore, this embodiment proposes a method for obtaining an accompanying relationship, including the following steps:

[0084]The first accompaniment relationship information acquisition step is to use the accompaniment relationship acquisition method based on the space-time trajectory to acquire the first accompaniment relationship information, wherein the unique coded information of the device can be a mac address and an imsi address, or a mac address and an IC card number , can also be a mac address, an imsi address, and an IC card number; and for a specific description about the method for acquiring the accompanying relationship based on the space-time trajectory, refer to the specific description of Embodiment 1, and will not repeat them;

[0085] The second concomitant relationship information acquisition step is to obtain the sec...

Abstract

The invention discloses an accompanying relationship acquisition method and system, equipment and a storage medium. The invention discloses a space-time trajectory-based adjoint relationship acquisition method and system. Identity features with space-time similarity corresponding to different individuals are acquired by excluding identity feature pairs with space-time similarity corresponding to the same individual, first adjoint relationship information is acquired by utilizing the identity features, and only data with space-time similarity and different individuals is calculated. Another aspect, The invention discloses an adjoint relationship obtaining method and system. A second adjoint relationship information among the virtual social identities is acquired according to the virtual social identities corresponding to the mac addresses, and the obtained first adjoint relationship information is utilized, fusion of the first adjoint relationship information and the second adjoint relationship information is realized according to the mac address, and the combined adjoint relationship information is obtained, so that the problem of data sparsity in the original method is effectivelysolved, and the breadth of identity characteristics in the adjoint relationship is further improved.

Description

technical field [0001] The present invention relates to the field of companion relation mining, in particular to a companion relation acquisition method, system, device and storage medium. Background technique [0002] A companion relationship is a relationship between two or more individuals that are related to a very close degree in time and space. [0003] With the development of science and technology, it is of great significance to use software to obtain the accompanying relationship between multiple individuals, which can help the police crack the case and improve the efficiency of solving the case. In the prior art, the acquisition methods of the accompanying relationship include: first, analyzing the spatio-temporal correlation of the actual travel trajectory data of the individual to obtain the accompanying relationship between individuals. This method not only has a large amount of calculation, but also obtains The data of accompanying relationship is sparse; the ...
