Research on News Text Classification Based on BERT-BiLSTM-TextCNN-Attention

Traditional machine learning models are difficult to capture complex features and contextual relationships. While a singular deep learning architecture surpasses machine learning in text processing, it falls short of encompassing the entirety of textual information [5]. Enter a novel approach: a news text classifier built upon BERT-BiLSTM-TextCNN-Attention. This model employs BERT's pre-trained language models to delve into text content. It then channels this data into a BiLSTM layer, capturing sequence nuances and long-term dependencies for comprehensive semantic insight. Following this, the output moves through a TextCNN layer, effectively capturing local semantic cues through convolution. The model culminates with attention mechanisms that highlight pivotal text attributes, refining feature vectors for the Softmax layer's classification. The experimentation utilized a subset of the THUCNews Chinese news text dataset. Results indicate that the BERT BiLSTM TextCNN Attention model achieved 96.48% accuracy, outperforming other benchmarks. This underscores its superiority in handling Chinese news text classification and validating its prowess in extracting deep semantic nuances and crucial local features from the text.
