- W4387541421 abstract "Unlike long texts, short texts can cause the problem of feature sparsity due to their short length. Although the existing deep learning-based methods alleviate this problem, the extracted semantic features are inevitably redundant, and the relationships between features are not fully considered when performing feature fusion, which in turn makes the semantics ambiguous and classification very difficult. To address the multi-feature fusion problem, we propose a Short Text Classification Model Based on Dynamic Routing and CNN with Attention Mechanism (DCAN). Firstly, we use Convolutional Neural Network (CNN) to extract text features with different granularity to enrich the semantic representation; secondly, we use attention mechanism and residual structure to fuse features with different granularity to obtain features with contextual semantic relationships, and then them into dynamic routing to obtain the probability distribution of short texts. We conducted experiments on four datasets, including AG News, MR, TREC, and SST-2. The experimental results show that DCAN has higher classification accuracy compared with most of the currently popular models." @default.
