Embodiment 1

[0069] The embodiment of this application provides a text classification method, please refer to Figure 1-a , the text classification method in the embodiment of the present application includes:

[0070] Step 101, perform text representation on the text to be classified, so as to obtain the sentence set of the above-mentioned text to be classified and the word set of each sentence;

[0071] Wherein, the sentence set is composed of a word set of each sentence in the text to be classified, and the word set is composed of word vectors of words included in the corresponding sentence.

[0072] In the embodiment of the present application, the text representation of the text to be classified may include two processes of preprocessing and vector representation. The above preprocessing refers to processing the text to be classified to obtain a structured representation, so as to obtain the sentence set of the above text to be classified and the word set of each sentence, and the abo...

Embodiment 2

[0152] An embodiment of the present application provides a text classification device. Such as Figure 2-a As shown, the text classification device in the embodiment of the present application includes:

[0153] The text representation unit 201 is configured to perform text representation on the text to be classified, so as to obtain a sentence set of the text to be classified, wherein the sentence set is composed of a word set of each sentence in the text to be classified, and the word set consists of The word vector composition of the words contained in the corresponding sentence;

Abstract

The invention provides a text classification method, a text classification device and a computer readable storage medium. The text classification method comprises the steps that text representation isconducted on a to-be-classified text to obtain a sentence set of the to-be-classified text, the sentence set is composed of word sets of all sentences in the to-be-classified text, and the word setsare composed of word vectors of words contained in corresponding sentences; based on a neural network, an attention mechanism and the word set, a feature vector of the sentence set is obtained; and the feature vectors of the sentence set is input into a text classification model to obtain a classification result of the to-be-classified text. According to the technical scheme, the text classification efficiency can be improved.

Description

technical field [0001] The present application belongs to the technical field of text classification, and in particular relates to a text classification method, a text classification device and a computer-readable storage medium. Background technique [0002] With the rapid development of the information age, a large amount of text information has accumulated in the Internet. In order to effectively manage and utilize these distributed massive information, content-based information retrieval and data mining have gradually become the areas of concern. [0003] Text classification technology is an important basis for information retrieval and text mining. Its main task is to classify the corresponding text according to the text content under the pre-given set of category tags. Text classification technology has a wide range of applications in natural language processing and understanding, information organization and management, content information filtering and other fields. ...
