DCAT: Combining Multisemantic Dual-Channel Attention Fusion for Text Classification
Kaifang Dong, Yifan Liu, Fuyong Xu, Peiyu Liu · IEEE Intelligent Systems · 2023
Text classification is a fundamental and central position in natural language processing. There are many solutions to the text classification problem, but few use the semantic combination of multiple perspectives to improve the classification performance. This article proposes a dual-channel attention network model called DCAT, which uses the complementarity between semantics to refine the understanding deficit. Specifically, DCAT first captures the logical semantics of the text through transductive learning and graph structure. Then, at the attention fusion layer (channel), we use logical semantics to perform joint semantic training on other semantics to correct the predictions of unlabeled test data incrementally. Experiments show that DCAT can achieve more accurate classification on a wide range of text classification datasets, which is vital for subsequent text mining tasks.
