This paper presents an Enhanced Extended Boolean Retrieval (EBR) framework that integrates Bidirectional Encoder Representations from Transformers (BERT) to address the shortcomings of traditional retrieval models, such as Term Frequency-Inverse Document Frequency (TF-IDF), which struggle with nuanced term relationships. The approach involves fine-tuning BERT and optimizing p-Norm values to enhance retrieval accuracy and query processing. Experimental results demonstrate that the Fine-Tuned BERT with EBR achieves 92% accuracy and an Area Under the Curve (AUC) of 0.92, outperforming the TF-IDF model’s 72% accuracy and traditional p-Norm models, which achieve around 83%. This hybrid framework ofers a balanced trade-of between precision and recall, proving effective for large-scale document retrieval. The study underscores the model’s scalability and robustness, highlighting its potential to enhance Information Retrieval (IR) systems for handling complex queries across various datasets.
