Idea
Model improving search relevance by self-evolving with multi-agent learning from massive real-world query streams.
Research Paper
Core Innovation
This paper introduces SERM, combining a multi-agent sample miner to detect distributional shifts and a multi-agent relevance annotator with a two-level agreement framework to generate reliable labels. This dual-agent approach addresses sparse informative samples and unreliable pseudo-labels in large-scale query streams, enabling effective self-evolution of relevance models.
Why It Matters
Search relevance models often fail to adapt to dynamic, large-scale query streams, leading to degraded user experience. SERM enhances relevance accuracy by continuously evolving with real-time data, enabling scalable and reliable search improvements. This approach supports billions of daily requests, making it critical for industrial search platforms.
Market Size (TAM)
$20–50B TAM for search relevance and AI-driven query understanding; $5–10B SAM from large-scale search engines and e-commerce platforms. Driven by increasing demand for personalized search and real-time model adaptation.
