Abstract

The invention relates to the technical field of artificial intelligence, and discloses a text classification method based on a neural network model, and the method comprises the steps: collecting textdata, carrying out the preprocessing of the text data, and obtaining the preprocessed text data; converting the preprocessed text data into a text vector; performing feature selection on the text vector by using a BP neural network classification model based on decision tree optimization to obtain an initial text feature; according to the obtained initial text features, training the BP neural network classification model by utilizing a stochastic gradient descent algorithm and a fin-turning method until the optimal text features are obtained; and according to the optimal text feature, classifying the text data by using a classifier, and outputting a classification result of the text data. The invention further provides a text classification device based on the neural network model and a computer readable storage medium. Accurate classification of the text data can be realized.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a neural network model-based text data classification method, device and computer-readable storage medium. Background technique [0002] With the rapid development of network technology, the requirements for the effective organization and management of electronic text information and the ability to quickly, accurately and comprehensively find relevant information are getting higher and higher. As a key technology for processing and organizing a large amount of text data, text classification solves the problem of messy information to a large extent and facilitates users to accurately obtain the required information. technical foundation. [0003] The prior art mainly builds a text classification model based on word frequency features in the text, and then performs text classification on the text to be classified based on the constructed text classification...
