Document Type and Number:
WIPO Patent Application WO/2021/081945
Kind Code:
A1
Abstract:
A text classification method and apparatus, and an electronic device and a storage medium. The method comprises acquiring a text to be classified; converting said text into a semantic matrix according to a semantic representation network of a pretrained text classification model; performing convolution operation on the semantic matrix in a convolutional layer of a semantic classification network of the text classification model, and obtaining multiple dimensions of semantic features; and determining a text category of said text in a classification layer according to the multiple dimensions of semantic features.
