The invention discloses a method and a device for monitoring network public opinions based on a neural network and a storage medium, and the method comprises the steps: carrying out the vocabulary segmentation of a training text in a preset duration, deleting a stop word, and obtaining a plurality of entries; determining the total number of categories to which the plurality of entries belong, andrespectively calculating the entry feature vector of each entry according to the total number of categories and the probability of each entry appearing in the training text; calculating the information entropy of each entry according to the entry feature vector; deleting entries of which the information entropies are smaller than preset information entropies to obtain a structured text; calculating the total number of text entry features in the structured text, taking the total number of text entry features as the number of input neurons of the neural network model, and determining the numberof output neurons and the number of hidden neurons of the neural network model according to the number of input neurons; randomly generating an initial weight of the neural network model; and performing sentiment analysis on the structured text based on the neural network model to obtain an output value, and determining a sentiment type of the structured text according to the output value.
Description
technical field [0001] The present application relates to the technical field of neural networks, in particular to a method, device and storage medium for monitoring network public opinion based on neural networks. Background technique [0002] Netizens express their opinions and attitudes on social phenomena and problems, making Internet public opinion more and more influential on society. Internet public opinion is a new concept that has emerged with the widespread use of the Internet in recent decades. It is the sum of the attitudes and emotions expressed by netizens or the media on a hot topic and issue in society, and it is the concentrated reflection of social public opinion on the Internet. Then its main feature is the spread through the Internet. In response to the public opinion crisis that may be caused by negative and negative public opinion information on the Internet, government departments and public opinion management agencies should establish a public opinio...
