An Integrated Framework Utilizing Hybrid LDA and BERT for Enhanced Hotel Recommendation Systems
摘要
In the ever-evolving hospitality industry, the need for advanced recommendation systems has become paramount, offering users personalized and dependable hotel suggestions. This paper represents a fusion of Latent Dirichlet Allocation (LDA) for topic modeling and Bidirectional Encoder Representations from Transformers (BERT) for sentiment analysis that enhances the accuracy and relevance of hotel recommendations, addressing the dynamic nature of user preferences. The first core component of our system harnesses the power of LDA topic modeling to unveil latent themes embedded within user-generated content, encompassing diverse sources such as reviews and hotel descriptions. Through this process, topics are categorized, granting the system deeper insights into various facets of hotels that forms the bedrock of more context-aware recommendations, enabling users to receive suggestions that align with their specific preferences and expectations. The second element of the system is the integration of BERT-based sentiment analysis. It undertakes a comprehensive exploration of user-generated content, deciphering the emotional sentiments expressed within the text by analyzing sentiment polarity and intensity. This personalized approach ensures that the system goes beyond the surface-level analysis, delivering a more tailored and satisfying user experience. To assess the efficiency and accuracy of the recommendation system, it is subjected to evaluation by comparing it with three other recommendation systems: LFM (Latent Factor Model), SVD (Singular Value Decomposition)++, and MFFR (Matrix Factorization Fusing Reviews). The benchmarking process employs two robust evaluation metrics, namely Accuracy Score and F-1 Score. Through this comparative analysis, the superior performance and precision achieved through the proposed system has been demonstrated.
