Abstract: To improve the effects of mathematical text classification as much as possible, by constructing a mathematical text dataset and analyzing the dataset, a multichannel attention mechanism-bidirectional encoder representation from transformers（MCA-BERT） model that enhanced the text entity information was proposed. Sentence-level entity information was obtained through the average pooling of the Word2vec word vector of entity words, different weights were assigned to different words through the atte... More
