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

Embodiment 1

[0063] Such as figure 1 As shown, this embodiment provides a method for constructing a multi-dimensional portrait of a group of people with a specific tendency, which specifically includes the following steps:

[0064] S1: Use the input method data source as the data source of the population to be analyzed;

[0065] S2: Construct at least one feature library according to the input method data source and actual requirements, the feature library has a set of at least one specific tendency feature;

[0066] S3: Match the input method data source of the population to be analyzed with the feature database, and screen out the target population with at least one specific tendency;

[0067] S4: Extract the input original text data of the target group, and build a single-channel target group portrait library based on the input method;

[0068] S5: Export the individual identification information in the single-channel target group portrait database, push it to each Internet platform, ...

Embodiment 2

[0104] This embodiment provides a system for constructing multi-dimensional portraits of people with specific tendencies, including:

[0105] The input method data source subsystem collects and stores the input method data information of the people to be analyzed;

[0106] A propensity feature library subsystem, which has at least one set of feature information with a specific propensity; and

[0107] The propensity matching subsystem compares the data information in the input method data source subsystem with the characteristic information in the propensity feature library subsystem, and marks the population with a specific tendency, and screens out people with at least one Target groups with specific tendencies;

[0108] The target group's network account subsystem associates the individual's network accounts on all Internet platforms according to the individual identification information of the target group;

[0109] The cross-Internet platform network data fusion subsyst...

Embodiment 3

[0143] This embodiment provides a method for constructing a multi-dimensional portrait of a group of people with a tendency, which specifically includes the following steps:

[0144] S1: Use the input method data source as the data source of the population to be analyzed;

[0145] S1.1 Multi-source data collection: collect data based on different input methods, including but not limited to: input text, input time, input platform, device identification code, registered account; the input methods include Tencent input method, Baidu input method, Sogou Input method, etc.; the data collected in this way has multiple sources and richness, which makes the data relatively complete and comprehensive, and facilitates the subsequent analysis and management of the target population;

[0146] S1.2 Multi-source heterogeneous data processing: preprocess the collected data, and remove noise information or blank information according to the cleaning mechanism or screening mechanism; the origi...

Abstract

The invention relates to a multi-dimensional portrait construction method for a crowd with specific tendency. The method specifically comprises the following steps: S1, taking an input method data source as a target crowd data source; s2, constructing at least one feature library of a set with at least one specific tendency feature according to an input method data source and actual requirements; s3, matching the input method data source of the to-be-analyzed crowd with the feature library, and screening out a target crowd with specific tendency; s4, extracting input original text data of the target crowd, and constructing a single-channel target crowd portrait library; s5, exporting individual identification class information, and associating network accounts of the individual existing in all Internet platforms; and S6, carrying out cross-Internet platform network data fusion: fusing heterogeneous network data of each Internet platform, adjusting the specific tendency of an individual according to an analysis result, forming a specific tendency target crowd multi-dimensional portrait library, and adjusting and perfecting the related tendency hierarchical feature library in the S2.

Description

technical field [0001] The invention relates to a method for constructing multi-dimensional portraits of people with specific tendencies. [0002] The invention also relates to a system for constructing multi-dimensional portraits of people with specific tendencies. Background technique [0003] With the popularization of mobile Internet and social media, the dissemination of various types of illegal information has intensified, the means of dissemination have become increasingly concealed, and the shortcomings 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 popularity of various network applications including cloud disks, instant messaging, forum blogs and online finance has made people with specific illegal tendencies use a large number of private and group-oriented network tools to incite, recruit,...
