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 concomitant relationship acquisition method based on a space-time trajectory, a accompanying relationship method based on a space-time trajectory comprising the steps of:

[0050] Time and space trajectory acquisition step, obtain the time and space trajectory information of the identity feature, identity feature is the unique encoded information indicating an individual, and the time-space trajectory information includes position information and time information, specifically, short trajectory information refers to the unique encoding information. The concrete time of the collected specific time and the acquisition device for collecting the device uniquely encoded information;

[0051] Identity Features For the acquisition step, determine the time and space similarity of any two identity features according to the time and space trajectory information to obtain an identity feature pair with time a...

Embodiment 1

[0076] Based on Example 1, Embodiment 2, a companion-based relationship acquisition system based on a space-time trajectory, including:

[0077] Time and space trajectory acquisition module, is used to obtain time and space trajectory information of identity features, identity feature to represent an individual's device uniquely encoded information, time and space trajectory information including location information and time information of identity feature;

[0078] The identity feature is used to obtain a time-space similarity of any two identity characteristics according to the time and space trajectory information to obtain an identity feature pair with time and space.

[0079] The identity feature pair the exclusion module, used to determine whether the identity feature having a time and space similarity pair whether the same individual is corresponding to the identity characteristics of the corresponding different individuals;

[0080] A accompanying relationship acquisition...

Embodiment 3

[0083] The cluster of the crowd exists in a group having a virtual social relationship, and also exists in a population with strong time and space. Therefore, this embodiment proposes a companion acquisition method, including the following steps:

[0084]The first accompanying information acquisition step, utilizing the accompanying relationship method obtaining method based on the time-space trajectory, wherein the device unique encoding information may be the MAC address and the IMSI address, or the MAC address and the IC card number. However, it can be a MAC address, an IMSI address, and an IC card number; and a specific description of the accompanying relationship acquisition method based on a space-time trajectory refers to the specific description of Example 1, it is not described again;

[0085] The second accompanying relational information acquisition step, based on the second accompanying relationship information between the virtual social identity according to the virtu...

Abstract

The present invention discloses a method, system, device and storage medium for acquiring an accompanying relationship. Among them, a method and system for acquiring an accompanying relationship based on a spatio-temporal trajectory obtains the According to the identity features corresponding to different individuals with temporal and spatial similarities, these identity features are used to obtain the first accompanying relationship information, and only data with temporal and spatial similarities and not the same individual are calculated. On the other hand, a method and system for acquiring a companion relationship in the present invention obtains the second companion relationship information existing between virtual social identities according to the virtual social identity corresponding to the mac address, and then uses the first companion relationship information obtained above , and then realize the fusion of the first accompanying relationship information and the second accompanying relationship information according to the mac address, and obtain the combined accompanying relationship information, which effectively makes up for the problem of data sparseness in the original method, and further improves the breadth of identity features in the accompanying relationship.

Description

Technical field [0001] The present invention relates to the field of accompanying relationship excavation, in particular a companion acquisition method, system, device, and storage medium. Background technique [0002] A accompanying relationship is a relationship between two or more individuals having a very close level in time and spatial dimensions. [0003] With the development of technology technology, it is important to help the police crack the case and improve the efficiency of the case with software acquisition. In the prior art, the acquisition method of accompanying relationship is: the first, the time and space association relationship of the individual's realistic travel trajectory data is analyzed to acquire the accompanying relationship between the individual, not only the amount is calculated, but also acquired Sparse with relationships; second, using virtual social identity to analyze the relationship analysis to obtain accompanying relationships, because the cor...
