Method and system for constructing multi-dimensional portraits of people with specific tendencies

Abstract

The present invention relates to a method for constructing multi-dimensional portraits of people with specific tendencies, which specifically includes the following steps S1: using input method data sources as the data source of target groups; S2: constructing at least one person with at least one specific tendency according to input method data sources and actual needs S3: Match the input method data source of the population to be analyzed with the feature database, and screen out the target population with specific tendencies; S4: Extract the input original text data of the target population, and construct a single Channel target group portrait library; S5: Export individual identification information, and associate the individual’s network accounts on all Internet platforms; S6: Cross-Internet platform network data fusion, fusion of heterogeneous network data of each Internet platform, according to The analysis results adjust the specific tendency of the individual to form a multi-dimensional portrait library of the target group with specific tendency, and adjust and improve the related tendency classification feature library in S2.

Description

technical field [0001] The invention relates to a method for constructing a multi-dimensional portrait of a specific tendency group. [0002] The invention also relates to a multi-dimensional portrait construction system of a specific tendency group. Background technique [0003] With the popularization of mobile Internet and social media, the dissemination of various illegal information has intensified, the means of dissemination have become increasingly concealed, and the deficiencies of existing monitoring methods have become increasingly prominent. The development of the Internet has brought unprecedented challenges for relevant departments to carry out special work such as anti-illegal activities. The popularization of various network applications, including cloud disks, instant messaging, forums and blogs, and online finance, makes people with specific illegal tendencies make extensive use of private and group-based network tools to incite, recruit, organize, plan and...

AI Technical Summary

Problems solved by technology

In recent years, the total amount of global Internet data has maintained a relatively high growth rate. On the one hand, the technical monitoring area is far behind the data growth rate of the entire network, and it is difficult to achieve results simply by adding human or technical resources; on the other hand, new technologies and applications of network communication have caused Monitoring blind spots mainly include closed communication platforms such as various social media, network disks, email groups, and instant messaging groups, as well as semi-closed communication platforms such as Moments, content sharing communities, and live barrage

As a result, the management and control of topical harmful information is "fortified layer by layer, and difficult to prevent layer by layer".

[0005] In addition, compared with conventional harmful information, the dissemination of various illegal information is more organized and purposeful, and has obvious characteristics: content production is more concealed, dissemination is circled and private, outbreaks are more random, and domestic and foreign exchanges are frequent

These characteristics make it very difficult to identify and monitor such harmful information, and it is difficult to find the source and predict in advance, but once it appears, it will cause extremely bad effects, resulting in a passive supervision situation.
