Network public sentiment hotspot prediction and analysis method

Abstract

The invention relates to a network public sentiment hotspot prediction and analysis method, which comprises the following steps: step (1) inputting public sentiment information collected in time into a hotspot public sentiment prediction model based on fast content identification; dividing the public sentiment information into hotspot public sentiment and ordinary public sentiment according to the processing results, and sending the pre-warning for the hotspot public sentiment; step (2), inputting the ordinary public sentiment into a hotspot prediction model based on numerical value expression, carrying out numerical value pattern matching on the input ordinary public sentiment information from the participating people number distribution and the time state distribution; and detecting the hotspot public sentiment information which is omitted in the detection in the first step; step 3, analyzing the hotspot public sentiment; and step 4, predicting the hotspot public sentiment. The invention combines the contents and the numerical values, and belongs to the integrated public sentiment hotspot monitoring method with the advantages of short prediction time and accurate prediction effect.

Description

technical field [0001] The invention relates to the field of network information security, more specifically, a method for predicting and analyzing hot spots of network public opinion.

Problems solved by technology

[0012] The main characteristics of the above three types of analysis methods are: the first and second types can judge hot information, but have obvious lag, and deal with the sudden shortage of hot public opinion information; the third type has a reasonable analysis process, but currently there is no There is no more mature and reasonable forecasting model

In addition, the above three types of analysis methods all analyze the content and numerical performance separately, which does not reflect the overall performance of public opinion well.
