Embodiment Construction

[0081] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0082] DT (Danger Theory) danger theory is a research theory in the artificial immune system; DCA (Dendritic Cell Algorithm) dendritic cell algorithm; PAMP (Pathogen-associated Molecular Patterns) pathogen-associated molecular patterns; DS (Danger Signal) danger signal ; SS (Safe Signal) safety signal; IS (Inflammatory Signal) inflammatory signal; CSM (costimulatory molecules) co-stimulatory molecules.

[0083] Principle of DCA algorithm: The DCA algorithm is mainly proposed by simulating the function of dendritic cells as antigen-presenting cells, and its input signals include four types: (1) PAMP signal (pathogen-as...

Abstract

The invention belongs to the technical field of microblog networks, and discloses a microblog water army detection method and system based on an artificial immunization danger theory. The method is characterized by applying an artificial immunization thought to the detection of the microblog user behavior characteristics and obtaining the microblog user data by using a focused web crawler; describing and defining network water army behaviors through an analysis method based on user behavior characteristics, and distinguishing characteristic attributes of novel network water army and normal users; and finally, applying a signal processing mechanism of an artificial immune danger theory to network water army detection, and detecting water army users in microblogs by adopting a dendritic cellalgorithm DCA of the danger theory. According to the method, the microblog user data is acquired in a Python-based focusing web crawler mode and stored in the database in a structured data mode, a data set is easily acquired in the mode, various behavior data of a user can be reasonably acquired, and the method has the advantages of being short in crawling period, high in data quality and the like.

Description

technical field [0001] The invention belongs to the technical field of microblog network, and in particular relates to a method and system for detecting microblog trolls based on artificial immune risk theory. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Microblogging trolls refer to those who are motivated by profit, in order to achieve the purpose of confusing the authenticity of information, guiding wrong public opinion, and harming the interests of citizens, by manipulating software robots or troll accounts to create and spread falsehoods on Weibo. Generic term for spam generators such as opinion and spam. Weibo troll detection uses some data mining techniques to define highly distinguishable features or behavior patterns to discover hidden cyber trolls. [0004] At present, the main water army detection methods are as follows: [0005] Trouble detection method based on content features: inc...
