E-commerce platforms are increasingly vulnerable to fake reviews, which can distort product ratings and mislead consumers. Detecting these fraudulent reviews is critical to maintaining trust and transparency in online marketplaces. This review provides a comprehensive analysis of deep learning techniques used for fake review detection. Key models such as Recurrent Neural Networks (RNNs), Long Short-Term Memory (LSTM) networks, and Transformer-based models like BERT are explored for their ability to analyze textual data and detect linguistic anomalies. Additionally, behavioral analysis using Convolutional Neural Networks (CNNs) and hybrid models combining textual and behavioral features are discussed. The review also highlights the role of Graph Neural Networks (GNNs) for network analysis and unsupervised learning methods like autoencoders for anomaly detection. Despite advances, challenges such as evolving fake review tactics, data imbalance, and cross-platform adaptability remain. The paper concludes by discussing future research directions, including enhancing model interpretability and combining deep learning with blockchain for more secure and verified review systems.
