Abstract

This study suggests and assesses a new book recommendation tool that uses large language models (LLMs) and vector search engines to handle the shortcomings of keyword-based systems. The use of LLMs allows the approach to gather meaning from what people write about the book and seek, which makes it possible for high-dimensional vector search engines to match these based on semantics. The system performs much better at recommending and making sense of information than traditional systems based on simulations. Essential mechanisms suggest that LLMs help users understand content better, and the use of vector searches speeds up and improves the comparison of semantic data, which results in better and more useful user experiences. By choosing this approach, it offers practical strategies to introduce books and bookshelves, and these strategies are useful and adjustable by various online services in this area. The method stands out by using semantic intelligence instead of metadata, making searching for information with AI better both in theory and practice.
