Abstract

The invention relates to the field of data monitoring, and discloses a risk identification method and device for public opinion data, computer equipment and a storage medium, and the method comprises the steps: obtaining public opinion data collected from a platform; identifying the public opinion data, and extracting feature information of the public opinion data; obtaining grade division of each piece of feature information from a feature database based on big data pre-collection, and matching a score value corresponding to the feature information according to the grade division of each piece of feature information; acquiring influence weights of the feature information, wherein the influence weights of the feature information are obtained based on historical public opinion data and risk marks of the historical public opinion data and through training of a machine learning algorithm; calculating a negative risk level of the public opinion data according to the influence weight of the feature information and the corresponding score value; and outputting the negative risk level of the public opinion data. The public opinion data can be accurately positioned, and the efficiency and accuracy of public opinion data risk identification are improved.

Description

technical field [0001] The present application relates to the field of data monitoring, and in particular, to a method, device, computer equipment and storage medium for risk identification of public opinion data.
