DianShi-RxnDB: A Large-Scale, Fine-Grained Organic Reaction Data Platform Built via a Fully Automated Pipeline for Researchers and AI Agents Researchers introduced DianShi-RxnDB, a large-scale, fine-grained organic reaction data platform built via a fully automated pipeline, aimed at researchers and AI agents developing artificial intelligence for chemistry (AI4Chem). The platform addresses the dispersal of high-quality structured organic reaction data across patent text, images, and reaction schemes. High-quality structured organic reaction data are essential for developing artificial intelligence for chemistry AI4Chem , yet much of this knowledge remains dispersed across patent text, images, and reaction schemes. We present DianShi-RxnDB, a large-scale, fine-grained organic reaction data platf
