Method, device and server for searching network information source

Abstract

Embodiments of the present invention provide a method, device and server for searching network information sources, which relate to the field of computer security. Through the semantic identification of public opinion information and the viscosity association analysis of social network nodes, it has the functions of information source network discovery and property identification. Compared with the traditional keyword semantic analysis and fixed-point information source relationship network extraction, this method combines phrase probability space and semantic joint matrix division method, naive Bayesian classification method to construct node semantic tree, node depth detection and vector conversion viscosity matching to extract information The source network, viscosity clustering algorithm and cross-correlation identify the final information source, which is more accurate and reasonable information source capture. Based on the same public opinion characteristic data, it has various analysis dimensions, social relationship analysis and public opinion characteristic identification, and data expression is more intuitive. The advantages. The detection object of the system is highly targeted, and it can analyze the deep-level characteristics of the data, detect the source network of public opinion, and easily find the source of social network information.

Description

technical field [0001] The invention relates to the field of computer security, in particular to a method, device and server for searching network information sources. Background technique [0002] With the rapid development of the Internet, the issue of network ideological security has received unprecedented attention. As the distributing center of today's ideology and culture and the amplifier of public opinion, the social network has reached an unprecedented level of activity on the Internet. Its directness, suddenness, and deviation make it a key object of social and government attention and monitoring. Rapid grasp of public opinion information, accurate prediction of public opinion trends, and rapid mining and identification of public opinion threat sources have become the key to public opinion security offensive and defensive warfare. The public opinion supervision model is completely helpless. At present, most public opinion identification and analysis methods are b...
