JD.com Launches Oxygen AIIC for Scalable E-commerce Item Understanding.

JD.com, a major global e-commerce platform, has unveiled the JD Oxygen AI Item Center (Oxygen AIIC), a sophisticated system designed to manage and understand its enormous catalog of products. Serving hundreds of millions of users and merchants with tens of billions of SKUs, the platform aims to improve customer experience, reduce operational costs, and boost efficiency through high-quality, structured item knowledge. Oxygen AIIC tackles key challenges such as rapidly evolving product concepts, the need for consistent knowledge across a massive inventory, and varied demands from different business functions. The Oxygen AIIC platform is built upon four foundational pillars. It employs human-AI collaboration for dynamic ontology engineering, supporting millions of entries. A "Semantic Search then Discrimination" (S2D) architecture, combined with throughput optimization, enables scalable production of an AI Item Library for billions of SKUs. The system also features self-evolving LLMs/VLMs for item understanding, achieving high precision and recall in knowledge production. Finally, a unified item tunnel acts as a central hub for data and services. This system is already deployed across core business areas like search and recommendations, demonstrating significant improvements in search traffic coverage, reduced item information quality issues, and increased automation in attribute filling.
