Embodiment 1

[0039] Procuratorial organs have accumulated a large amount of case-handling data through the process of informatization. Therefore, this patent is based on the closed case data, adopts the rough set method, screens out the data that plays a role in the case analysis from various data, removes the redundant data that does not play a role in the case analysis, and conducts important analysis on various data sources. Sexual order, so as to provide assistance for actual case handling. Its main process is as follows:

[0040] 1. Construction of social network

[0041] For a specific job crime case, a corresponding social network graph can be constructed based on data from different sources. Each type of social network can be abstracted into a graph G(V, E), where the vertex set V represents all persons involved in the case, and the edge set E represents the social relationship of all persons involved in the case, that is, if there is a corresponding social relationship between t...

Embodiment 2

[0073] In this embodiment, in combination with specific data, it is assumed that an analysis of a closed case is carried out. The main suspect involved in this case is a certain leader A of W City. The social network is analyzed and summarized, and the conclusion is as follows: Figure 7 The social relationship network of each social network source is refined as follows: Figure 8 detailed social network of Figure 8 The four relationship diagrams in are marked as (a), (b), (c) and (d) from left to right and from top to bottom; Figure 8 (a) Indicates the detailed social relations of criminal suspect A's work circle, Figure 8 (b) indicates the detailed social relationship of criminal suspect A's entertainment circle, Figure 8 (c) indicates the detailed social relationship of criminal suspect A's network communication circle, Figure 8 (d) indicates the detailed social relationship of criminal suspect A's circle of friends. Then convert each detailed social relationship ...

Abstract

The present invention belongs to the field of duty-related crimes, and relates to social network analysis, specifically a method and system for intelligently analyzing the social network of job-related crimes based on rough sets. The method includes classifying the social network of criminals in closed cases, And based on the rough set, intelligently analyze the social network, find the clues that play a key role in the case, and remove the irrelevant clues; based on the closed case data, use the rough set method to filter out the case analysis from various data Effective data, remove redundant data that is ineffective for case analysis, and sort the importance of various data sources, so as to provide assistance for actual case handling.

Description

technical field [0001] The invention belongs to the technical field of big data analysis, relates to social relationship network analysis, and is specifically a rough set-based intelligent analysis method and system for a social relationship network of job-related crimes. Background technique [0002] In the investigation of duty crimes, the social network of criminal suspects is the key to case analysis. In actual cases, the criminal suspect's social network is generally very large and complex, including relatives, classmates, work, etc., and the construction of these relationships needs to be mined from various data sources. For example, Chinese patent CN103714126B proposes a The method and device for pushing book reading services can effectively mine data, thereby effectively promoting young people to improve their reading skills and reading interest in the process of learning and growing up. How to construct the social network of criminal suspects from various data sour...
