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...
