Research Paper Overview
End-to-End Aspect-Guided Review Summarization at Scale
Summary
This paper presents a scalable system combining aspect-based sentiment analysis with guided summarization to generate concise product review summaries. It extracts aspect-sentiment pairs from reviews, selects frequent aspects per product, and uses structured prompts to guide a large language model in producing summaries grounded in real customer feedback. The system is validated through a large-scale online A/B test and deployed in real-time on the Wayfair platform. Additionally, an anonymized dataset of 11.8 million reviews with extracted aspects and summaries is released to support future research.
