Start here — what's in this sample, how it's labeled, and getting the full dataset
Welcome 👋 This is a free sample of MatrixNorm's structured Board of Veterans' Appeals (BVA) decisions.
What it is: each decision is normalized into machine-readable fields —
issue → condition → outcome (granted/denied/remanded) → cited authority (38 CFR / U.S.C. / diagnostic code) → reasoning, with provenance back to the source decision on <va.gov>.
Coverage in this sample: ~2,900 decisions, 2019–2025.
Label honesty (important): labels in this sample are silver — produced by a deterministic, schema-driven extractor (rule + LLM-assisted), ~96% field accuracy on internal checks. A human-verified gold subset is in progress and will be noted when released. Recall on the core fields is high; please open a discussion if you spot an error.
License: CC-BY-NC-4.0 — free for research and evaluation. Commercial use requires a separate license (and the full corpus, additional fields, and the gold set are available commercially). Contact: [your email].
Requests welcome: tell us the conditions, fields, or date ranges you need and we'll prioritize them.
