Deep Learning Based Text Classification: A Comprehensive Review
This is a review paper that synthesizes existing work for researchers in natural language processing, making it incremental in nature.
The paper reviews over 150 deep learning models for text classification, summarizing their contributions and analyzing performance on benchmarks, but does not present new experimental results or specific numerical gains.
Deep learning based models have surpassed classical machine learning based approaches in various text classification tasks, including sentiment analysis, news categorization, question answering, and natural language inference. In this paper, we provide a comprehensive review of more than 150 deep learning based models for text classification developed in recent years, and discuss their technical contributions, similarities, and strengths. We also provide a summary of more than 40 popular datasets widely used for text classification. Finally, we provide a quantitative analysis of the performance of different deep learning models on popular benchmarks, and discuss future research directions.
