ORDerly: Styrene Mizoroki-Heck RAG-Ready Dataset
This repository contains chemical reaction data formatted for Retrieval-Augmented Generation (RAG) systems.
The data is a processed version of the ORDerly benchmark, specifically focusing on reaction conditions and forward/retro prediction tasks.
Dataset Structure
The data is split into 10,000-row Parquet chunks to prevent Out-of-Memory (OOM) errors during ingestion into vector databases.
It includes:

EditScore-shaped corpus: one root row per intent, three candidates per row (rank1 the
reference diagram, rank3 one that compiles and does the wrong thing, rank5 one the
compiler refuses), and one score row per candidate from the compiler's reference scan on three constructed input traces per row. Every row is

Skin_Reaction record-level transfer V19.1
This indirect-only dataset retains individual eligible numeric records from exact Stage-3 assay
buckets with at least 20 proper-train parents. Each prompt shows A's and B's own assay details;
only A shows measurement and result-bearing evidence. Validation is held out from source train;
test uses the selected-gold validation scaffold universe. Rankings use 20 Morgan-nearest train
parents.

reuse V9 exactly. Indirect validation is held out from source train, while indirect test uses
the frozen Starling validation scaffold universe; each indirect panel has 20 Morgan-nearest
proper-train parents.
