abstract = {In the modern hospitality landscape, the exponential growth of online consumer-generated content has rendered manual sentiment monitoring nearly impossible. This research proposes a robust, real-time sentiment analysis framework for hotel reviews leveraging the Bidirectional Encoder Representations from Transformers (BERT) architecture. Unlike traditional Lexicon-based or Recurrent Neural Network (RNN) approaches that process text unit-directionally, our system utilizes the transformer-based attention mechanism to capture bidirectional context, effectively identifying nuanced sentiments like sarcasm, negation, and domain-specific terminology (e.g., "room service was a bit of a stretch").The methodology encompasses a rigorous data pipeline: raw review acquisition, text normalization, and tokenization via the Word Piece algorithm. We fine-tuned the $BERT_{BASE}$ model on a diverse dataset of multi-lingual hotel reviews, optimizing hyperparameters such as learning rate and dropout probability to prevent overfitting. Experimental results demonstrate that the proposed model achieves an Accuracy of 94.2% and an F1-score of 0.93, significantly outperforming baseline models like LSTM and Support Vector Machines (SVM). Furthermore, we implement a low-latency inference layer that allows hotel management to categorize feedback into positive, negative, or neutral sentiments in real-time. This system provides an actionable tool for the hospitality industry to enhance service quality, manage brand reputation, and respond dynamically to customer dissatisfaction.},
