Abstract: 【Purpose/significance】Aiming at the problems of large perception error and low sensitivity in existing network public opin?
ion situational awareness methods, this paper studies the network public opinion situational awareness method from the perspective of ideology.【Method/process】This paper firstly introduces the basic concepts and characteristics of network public opinion situation
awareness and the security structure of network public opinion situation awareness; Then, from the perspective of ideology, a percep?
tion method for capturing and processing network public opinion situational awareness data, identifying network public opinion situ?
ational awareness vulnerability and detecting network public opinion situational awareness behavior events is proposed; Finally, the
method of network public opinion situation awareness is tested and studied by taking network public events as the research object.
【Result/conclusion】The example analysis results show that the perception error of the designed situational awareness method is less than 1, and the time-consuming time is less than 5s, that is, the designed method has good perception accuracy and sensitivity.【Inno?vation/limitation】But in terms of feature extraction, the proposed method does not involve suitable predictive features. Therefore, in the follow-up research process, the different characteristics of network public opinion situation awareness methods should be fully con? sidered, and new thinking should be carried out according to the actual development situation.
