Network information source searching method and device and server

Abstract

The embodiment of the invention provides a network information source searching method and device and a server, and relate to the field of computer security. Through public opinion information semantic recognition and social network node viscosity association analysis, the device is endowed with functions of information source network discovery and property recognition. Compared with traditional keyword semantic analysis and fixed point information source relation network extraction, a node semantic tree is constructed by combining phrase probability space, a semantic joint matrix division method and a naive Bayes classification method, an information source network is extracted by means of node depth detection and vector conversion viscosity matching, a final information source is identified by means of a viscosity clustering algorithm and cross-correlation, and the more accurate and reasonable information source is captured, so that on the basis of same public opinion characteristicdata, the method has the advantages that the analysis dimensions are diverse, the social relation analysis and the public opinion characteristic identification are deep, and the data expression is more visual. Detection objects of a system is highly targeted, the deep characteristics of the data can be analyzed, the public opinion source network is detected, and the social network information source is easily discovered.

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...
