Abstract

This chapter delves into the challenge of limited product reviews for new or less popular items and proposes a solution by leveraging opinions from similar products. The study introduces a method that uses a Large Language Model (LLM) to identify relevant attributes and retrieve opinions from similar products, enhancing user decision-making. The research evaluates the effectiveness of this approach through both automatic and human evaluations, demonstrating that the proposed method outperforms baseline methods. Key topics include the transformation of text queries into attribute queries, the retrieval of similar products based on attribute similarity, and the extraction and ranking of opinions from product reviews. The study concludes that using opinions from similar products can significantly improve the quality of information available to users, making it a valuable tool for e-commerce platforms and retailers.
