System and method for mining target personnel based on time association of theme event

Abstract

The invention provides a system and a method for mining target personnel based on time association of subject events. The system comprises a data acquisition module, an interactive data import module, a data processing module, an algorithm analysis module, a joint mining module and a target personnel discrimination module. According to the method, data cleaning, data desensitization and key person marking are carried out on interaction records of dominant key persons, a query mode is judged according to recorded interaction time, then associated persons are screened, and an association Re value is calculated. According to the method, the target personnel, namely the hidden high-risk key personnel, are screened out by taking the communication between the key personnel or the relevance before and after the transfer transaction behavior as an effective entry, so that the research and judgment efficiency is improved while law enforcement and research and judgment clues are expanded, line expansion investigation, point-to-surface investigation and person-to-case investigation are realized, and the research and judgment efficiency is improved. And the actual combat efficiency of using new technologies and new means to serve intelligent public security is fully improved.

Description

technical field [0001] The invention relates to the technical field of network analysis and data mining, and in particular, to a system and method for mining target persons based on temporal association of subject events. Background technique [0002] In the era of big data, the field of investigation is also facing an unprecedented historical change as the application of new technologies such as mobile internet and the public's daily life are increasingly connected. For the obtained intelligence clues, the traditional investigation mode mainly relies on manual investigation. Although the accuracy of manual screening is high, it is faced with intricate communication records, instant chats, transfer transactions and other massive interactive data between people. , there are problems such as low efficiency, high cost, and lack of human resources, which make it difficult for traditional manual screening to be popularized and applied on a large scale. [0003] Therefore, in the...

Problems solved by technology

In addition, some algorithms have a high rate of misjudgment. The target personnel excavated are found to be the top-up number of the operator, the express driver, the takeaway, and the courier, etc.
