Researchers have developed a new Large Language Model (LLM) based re-ranker to improve conversational search for real estate. This system augments existing recommendation engines by reordering property listings based on the nuanced, multi-turn dialogue expressed by users. An extensive evaluation dataset was created using an LLM-as-a-Judge framework with human validation, comprising 960,000 query-item pairs. The approach demonstrated significant improvements in ranking quality, leading to a 5.3% increase in click-through rate and a 4.8% rise in scheduled visits during a production A/B test. AI
