Abstract

The invention discloses an intelligent mining system for sensitive information in public opinion information, and the system comprises: a public opinion information preprocessing module which is usedfor filtering impurity information in the public opinion information, and obtaining filtered public opinion information; a sensitive information category labeling module which is used for receiving and recording manual labeling information on an information display interface to obtain labeled public opinion information; a bert model-based sensitive information identification module which is used for training a sensitive information classification model according to the marked public opinion information to obtain a mining model; a public opinion information sensitive intelligent mining module which is used for intelligently mining public opinion information in real time according to the mining model and outputting a mining result; and a sensitive information visualization module which is used for displaying the public opinion information and the mining result on an information display interface in a visual form. By the adoption of the system, sensitive intelligent mining of public opinion information can be completed in combination with the requirements of public opinion workers, the public opinion workers can conveniently know and master the public opinion information in real time,and related workers are assisted to complete decision making.

Description

Technical field [0001] The invention relates to the field of intelligent analysis of public opinion data, in particular to an intelligent mining system for sensitive information in public opinion information based on actual needs of users. Background technique [0002] With the development of the new era, the Internet has gradually become the main medium for people to disseminate and obtain various information. Online information is complex and complicated, which increases the time cost for public opinion workers to mine information. How can we dig out massive public opinions faster and more effectively? The key public opinion information in the information is an urgent problem to be solved. [0003] In the prior art, the sensitive information mining of the public opinion system mainly relies on the sensitive word hit method to identify the sensitive information. However, due to the continuous appearance of new words, it is difficult for the lexicon to fully cover the sensitive wor...
